Headed towards a 4.0. The binary format will change slightly but

The new non-libltdl foreign library loading algorithm from 3.0.6
fails to cover common cases regarding how libtool names and installs
DLL files. Notably, it fails to recognize when libtool has added the
major version number into the filename itself, such as libfoo-1.dll
Also, it does not search in binary directories and the PATH for DLL
files, where libtool is likely to install DLLs.
This adds the option to search for dlls with major version numbers
in the filename, and modifies the search strategy for DLL-using
OSs to check bindir and PATH.
For MSYS, libraries are installed with the 'msys-' prefix. So this
modifies load-foreign-library to handle that prefix as well.
It changes the #:rename-on-cygwin? option to #:host-type-rename? to
better reflect that is works on both Cygwin and MSYS.
Partially based on a patch by Hannes Müller.
* NEWS: updated
* doc/ref/api-foreign.texi: document updates to load-foreign-library
and system-dll-path
* module/system/foreign-library.scm (is-integer-string?): new utility function

(file-exists-in-path-with-extension): add flag argument to all new dll search
(system-dll-path): new parameter
(lib->msys): new helper function
(load-foreign-library): add new optarg flag #:allow-dll-version-suffix?
Pass new flag to library search functions.
Implement new search strategy for #:search-system-paths? on DLL systems'
replace #:rename-on-cygwin? with #:host-type-rename?
Use that option to rename both MSYS and Cygwin libraries.
(guile-system-extensions-path): prefer bindir to libdir on DLL systems
* test-suite/tests/foreign.test ("dll-name-match?"): new test category
("find-best-dll-from-matches"): new test category
("lib->msys"): new unit tests
Fixes <https://bugs.gnu.org/30600>.
* module/system/repl/command.scm (define-meta-command): Flush all
remaining input after handling a read error.
* module/system/repl/common.scm (flush-all-input): New public procedure.
* module/system/repl/repl.scm: Remove local flush-all-input definition.
The builtin primitive procedure `error` takes an optional message and
a list of arguments to include into the error message.
These args are formatted with `~S` and appended to the error message, so
that an example call of
`(error "Wrong argument: " 42)`
results in the output
"Wrong argument: 42"
If format strings occur in the message itself, however, they are
escaped. Thus a call like
`(error "Wrong argument: ~a" 42)`
is rendered as
"Wrong argument: ~a 42"
Some callers did not take this behavior into account, leading to
confusing error messages.
Changing the behavior of `error` to be
both backwards-compatible and accept also format strings inside messages
is not straightforward, because it would have to handle escaped `~`
characters as well. Therefore, fix `error` call sites using format
strings to use `format` before calling out to `error`.
The following files are affected:
* module/ice-9/format.scm (format)
* module/ice-9/r6rs-libraries.scm (resolve-r6rs-interface)
* module/oop/goops.scm (make)
* module/srfi/srfi-37.scm (Comment at the beginning of file)
* module/system/base/compile.scm (call-once)
* module/system/repl/command.scm (break, tracepoint)
* module/system/repl/common.scm (repl-default-options)
* module/system/vm/traps.scm (arg-check, trap-at-source-location)
There are a couple of further call sites that were left unchanged,
either because they are using their own `error` procedure:
* module/ice-9/read.scm
* module/ice-9/command-line.scm
or are not referenced from other modules:
* module/system/base/lalr.upstream.scm:
* module/sxml/upstream/assert.scm:
* module/sxml/sxml-match.ss:

Fixes a regression introduced in
4a0c2433d9: the strategy wouldn’t work
when writing to, say, a bytevector output port.
* module/system/vm/linker.scm (link-elf)[write-padding]: Reintroduce
loop for when PORT is not a file port. Remove first argument.
Since ‘*lcm-page-size*’ is 64 KiB, this saves disk space for small ‘.go’
files.
* module/system/vm/linker.scm (link-elf)[write-padding]: Rewrite in
terms of ‘seek’.
* module/system/foreign.scm (read-fields, write-fields): Don't return
the final offset, as the offset after the final field is not necessarily
the end of the struct, because of padding.

* libguile/foreign.h:
* libguile/foreign.c: Always define complex-float and complex-double.
Fall back to alignof float / 2*sizeof float if no complex numbers. (But
with C99 surely it exists everywhere.)
* module/system/foreign.scm (*writers*, *readers*): Always include
complex-float and complex-double readers and writers.
* test-suite/tests/foreign.test: Always run the complex tests.

Add string->utf8, utf8->string, and string-utf8-length.
* module/language/tree-il/compile-cps.scm (string->utf8)
(string-utf8-length, utf8->string): New custom lowerers, including type
checks and an unboxed result for string-utf8-length.
* module/system/vm/assembler.scm:
* libguile/intrinsics.h:
* libguile/intrinsics.c: Because string-utf8-length returns an unboxed
value, we need an intrinsic for it; go ahead and add an intrinsic for
string->utf8 and utf8->string too, as we will likely be able to use
these in the future.
Recognize `raise-exception` in the same way we recognize `throw`, though
it is a bit less optimized and the boot story is not as complicated.
* doc/ref/vm.texi (Non-Local Control Flow Instructions):

(compile_unreachable_slow):
* libguile/vm-engine.c (VM_NAME):

This reduces the amount of memory that needs to be allocated while
writing the ELF file to disk.
Note: We're abusing #:page-aligned? in 'link-elf' to choose whether to
return a bytevector or a procedure.
* module/system/vm/linker.scm (process-reloc): Subtract SECTION-OFFSET
when writing to BV.
(write-linker-object): Pass BV directly to the linker object writer.

procedure instead of a bytevector.
(bytecode) <#:printer>: Likewise.
* test-suite/tests/linker.test (link-elf-with-one-main-section): Pass
#:page-aligned? #f.

and add 'size' and 'writer'.
