* libguile/vm-i-system.c (call_cc, tail_call_cc): Call the new
RESTORE_CONTINUATION_HOOK when a continuation is restored.
(prompt): Call the new ABORT_CONTINUATION_HOOK when entering the abort
handler's continuation.
* libguile/vm-engine.h (ABORT_CONTINUATION_HOOK)
(RESTORE_CONTINUATION_HOOK):
* libguile/vm.h (SCM_VM_ABORT_CONTINUATION_HOOK)
(SCM_VM_RESTORE_CONTINUATION_HOOK):
* libguile/vm.c: (scm_vm_abort_continuation_hook): New hook, called when
entering an abort handler.
(scm_vm_restore_continuation_hook): New hook, called after returning
to a continuation.
* module/system/vm/vm.scm: Add hooks to export list.
* libguile/vm.h (SCM_VM_PUSH_CONTINUATION_HOOK)
(SCM_VM_POP_CONTINUATION_HOOK): New hooks, to replace
enter/exit/return.
(SCM_VM_BOOT_HOOK, SCM_VM_HALT_HOOK, SCM_VM_BREAK_HOOK): Remove these
useless hooks.
* libguile/vm.c (scm_vm_push_continuation_hook)
(scm_vm_pop_continuation_hook): New accessors.
* libguile/vm-i-system.c: Remove boot, halt, break, enter, exit, and
return hooks. Also remove the break instruction. Instead now when we
push a new continuation onto the stack we call PUSH_CONTINUATION_HOOK,
and when we pop via a return we call POP_CONTINUATION_HOOK. APPLY_HOOK
is now decoupled from continuation pushes and pops.
* libguile/vm-engine.h:
* libguile/vm-engine.c: Adapt for hooks.

Reported by Mike Gran <spk121@yahoo.com>.
* libguile/strings.c (scm_i_unistring_escapes_to_guile_escapes,
scm_i_unistring_escapes_to_r6rs_escapes): Augment comments.
(scm_to_stringn): When `handler ==
SCM_FAILED_CONVERSION_ESCAPE_SEQUENCE && SCM_R6RS_ESCAPES_P', realloc
BUF so that it's large enough for the worst case.
* libguile/print.c (display_character): When `result != NULL && strategy
== SCM_FAILED_CONVERSION_ESCAPE_SEQUENCE && SCM_R6RS_ESCAPES_P', make
LOCALE_ENCODED large enough to hold an R6RS escape.
This makes `peek-char' 40x faster on a port whose encoding is
faster on a UTF-8 port containing multi-byte codepoints.
The `xml->sxml' procedure is 4x faster on a 2.7 MiB XML file.
* libguile/ports.c (get_codepoint): New procedure, moved here from
`scm_getc', with the additional BUF and LEN parameters.
(scm_getc): Use it.
(scm_peek_char): Use it instead of the `scm_getc'/`scm_ungetc'
sequence.

"peek-char [utf-8]"]: New tests.
* benchmark-suite/Makefile.am (SCM_BENCHMARKS): Add
`benchmarks/ports.bm'.
* benchmark-suite/benchmarks/ports.bm: New file.
This had been removed by commit 07f49ac786
("Factorize and optimize `write' for strings and characters.").
Thanks Mike!
* libguile/print.c (write_combining_character): New procedure.
(write_character): Use it.
* test-suite/tests/chars.test ("basic char handling")["combining accent
is pretty-printed", "combining X is pretty-printed"]: New tests.

`SCM_WRITINGP (pstate)' and `SCM_CHARP (exp)' or `scm_is_string (exp)'.
(scm_i_charprint): Remove.
(display_character, write_character): New functions.
(scm_write_char): Use `display_character' instead of
`scm_i_charprint'.
* libguile/print.h (scm_i_charprint): Remove declaration.
* benchmark-suite/benchmarks/write.bm: New file.
* benchmark-suite/Makefile.am (SCM_BENCHMARKS): Add
`benchmarks/write.bm'.
* libguile/srfi-1.c:
* libguile/srfi-1.h:
* libguile/srfi-60.c:
* libguile/srfi-60.h:
* libguile/ChangeLog-srfi: Move here, from the srfi/ dir. The C API is
internal. Add API to register the extensions, called by init.c.

* libguile/strings.c (scm_to_latin1_stringn): new function
(scm_from_latin1_stringn): new function
* libguile/numbers.c (scm_log10): Check whether `HAVE_COMPLEX_DOUBLE'
and `HAVE_CLOG10' are defined instead of checking whether they are
non-zero.
(scm_sqrt): Likewise for `HAVE_COMPLEX_DOUBLE' and
`HAVE_USABLE_CSQRT'.
This updates Gnulib to v0.0-4219-g84cdd8b.
* m4/gnulib-cache.m4: Add `isinf' and `isnan'.
* configure.ac: Remove checks for `floatingpoint.h', `ieeefp.h', and

`SCM_HAVE_FLOATINGPOINT_H', `SCM_HAVE_IEEEFP_H', or `SCM_HAVE_NAN_H'.
Suggested by primus <rprimus@gmail.com>.
* configure.ac: Use `AC_LIB_HAVE_LINKFLAGS' when checking for libltdl.
* libguile/Makefile.am (libguile_@GUILE_EFFECTIVE_VERSION@_la_LIBADD):
Add $(LTLIBLTDL).
* README: Update to make it clear that libgc and libffi don't have a
`--with-XXX-prefix' option.
* libguile/programs.c (scm_program_module): Fix an edge case in which
this function returned non-modules. Thanks to José Antonio Ortega
Ruiz, Caballero del Cálculo Lambda for the report.
* libguile/load.c (compiled_is_fresh): Don't emit "source file is newer"
warning when either FULL_FILENAME or COMPILED_FILENAME could not be
stat'd. This is consistent with what load/compiled-file-name do.
* libguile/load.c (compiled_is_fresh): Rename `res' to
`compiled_is_newer'. Use `get_stat_mtime' to compare with nano-second
resolution when available.
* module/ice-9/boot-9.scm (load)[fresh-compiled-file-name]: Likewise,
using `stat:mtimensec'.
* libguile/foreign.c (make_cif): New procedure, with code formerly in
`scm_make_foreign_function'.
(scm_make_foreign_function): Use it.
(invoke_closure, scm_procedure_to_pointer)[FFI_CLOSURES]: New
functions.

procedures and related tests.
* test-suite/standalone/test-ffi-lib.c (test_ffi_callback_1,
test_ffi_callback_2): New functions.

* doc/ref/api-foreign.texi (Dynamic FFI): Document `procedure->pointer'.
The memory leak is trivially reproducible with:
(define m (make-mutex))
(let loop () (lock-mutex m) (unlock-mutex m) (loop))
or similarly with:
(define p (delay (+ 1 2)))
(let loop () (force p) (loop))
since `force' acquires P's mutex.
It could also lead to premature release of a thread waiting in
`fat_mutex_lock' when a former owner's `do_thread_exit' is run.
* libguile/threads.c (fat_mutex_unlock): When `m->level' becomes 0,
remove MUTEX from `t->mutexes'.
(fat_mutex_lock): Update comment above the `t->mutexes' assignment.
(do_thread_exit): Add an assertion making sure that each mutex in
`t->mutexes' is owned by T.
* test-suite/Makefile.am:
* test-suite/tests/bitvectors.test: Add a new file to test bitvectors.
* libguile/uniform.c (scm_c_uniform_vector_length): Don't call
scm_uniform_vector_elements, as we don't need to be able to access the
elements with pointers to bytes. Fixes uniform-vector-length on
bitvectors.
* libguile/struct.h (SCM_VTABLE_FLAG_VALIDATED): New flag, indicates
that the layout of a vtable has been validated. The other flags have
been renumbered.
* libguile/struct.c (scm_i_struct_inherit_vtable_magic): Set the
VALIDATED flag if everything goes through.
(scm_struct_vtable_p): If the struct should be a vtable but isn't
validated, throw an error.
(scm_make_vtable_vtable): Validate the incoming user_fields layout
bit. Set the VALIDATED flag.
(scm_c_make_structv): Add a comment about the case in which we delay
scm_i_struct_inherit_vtable_magic.
* libguile/deprecation.c (scm_c_issue_deprecation_warning):
* libguile/extensions.c (scm_c_register_extension, load_extension): Add
locks around global data structures.
This reverts commit 6832604efa. Not only
does this fail on a fresh build due to a lack of "guile", but even if it
did have its Makefile fixed, it would take too long to run, because the
rest of Guile isn't compiled.
The right thing is to avoid invoking Guile until after at least psyntax
and boot-9 have been compiled.
This commit can be reinstated if we move doc snarfing to a phase that
happens after module/ is compiled.
* libguile/guile-snarf-docs.in: Rewrite to incorporate all
three phases of snarfing: func-name check, cpp, tokenization.
Also, require/check new command-line syntax.
* libguile/Makefile.am (AM_V_FILTER): Delete var.
(AM_V_FILTER_, AM_V_FILTER_0): Likewise.
(.c.doc): Run ./guile-snarf-docs; use new command-line syntax.
* configure.ac (sitedir): Fix definition to point to the
version-specific sitedir.
* libguile/Makefile.am (libpath.h): Take sitedir definition from
configure.ac.
* libguile/foreign.c (scm_string_to_pointer, scm_pointer_to_string): New
functions.
* libguile/foreign.h (scm_string_to_pointer, scm_pointer_to_string): New
declarations.
* module/system/foreign.scm: Export `string->pointer' and
`pointer->string'.
* test-suite/tests/foreign.test ("pointer<->string"): New test prefix.
* doc/ref/api-foreign.texi (Void Pointers and Byte Access): Add
`string->pointer' and `pointer->string'.
* libguile/Makefile.am:
* libguile/discouraged.c: Remove discouraged.c.
* libguile/deprecated.c:
* libguile/deprecated.h:
* libguile/discouraged.h: All functions and declarations moved from
discouraged.[ch] to deprecated.[ch], adding deprecation warnings.
* libguile/init.c: Remove discouraged init.
* libguile/numbers.c (scm_num2float, scm_num2double): Deprecate.
* test-suite/standalone/test-num2integral.c: Port to modern API.
* libguile/foreign.c (scm_i_pointer_print): Print in hexadecimal.
* doc/ref/api-foreign.texi (Modules and Extensions): Update for
"extensiondir", and a discussion of Guile versions.
(Foreign Variables): Fix discussion of types.
(Void Pointers and Byte Access): Fix typo.
* libguile/load.h:
* libguile/load.c (scm_sys_global_site_dir): New API, is what %site-dir
used to be.
(scm_sys_site_dir): Changed to be a version-specific dir.
(scm_init_load_path): Search the version-specific sitedir before the
global one.
