On Windows, deleting a file on an open port does not succeed

ensure port is closed before deleting

Adapted from a patch by Rob Browning.
The underlying function was moved to filesys.c in
073167ef7b but the declaration didn't follow

include SCM_RDNG for input/output ports.
Thanks to Göran Weinholt for reporting the problem.
Closes: 41045

already does.
Thanks to Erik Dominikus for reporting the problem.
Closes: 43304
The line, part of the sentence above it in a comment, was accidentally
removed in commit b8d757732f "Rationalize
include order in C files".

via (ice-9 ports).

(call-with-output-bytevector): New functions.
* module/ice-9/iconv.scm: Remove superfluous copies of
call-with-output-string* and call-with-output-bytevector*, now that
the former closes the port and the latter exists.
(call-with-encoded-output-string): Adapt.

bytevector/string conversion procedures.

multiple

new warning types.
* test-suite/tests/tree-il.test: Add tests.
* doc/ref/api-evaluation.texi (Compilation): Update.
* libguile/gc.c (DEFAULT_INITIAL_HEAP_SIZE): Bump a bit farther (2 MB on
64-bit, 1 MB on 32-bit) as we now expand to this size instead of
expanding by this amount.
(scm_storage_prehistory): Expand to the initial heap size instead of
expanding by the size.
* libguile/gc.c (DEFAULT_INITIAL_HEAP_SIZE): Bump to 1.6 MB on 64-bit
targets, or 800 kB on 32-bit targets, to account for increased
footprint. Prevents useless early GC.

(propagate-analysis, eliminate-common-subexpressions-in-fun): Plumb
consts through the algorithm.
(fold-branch): Fold an eq-constant? using the flow-determined constant
info. Finally allows compile-bytecode to fold to switch statements!

branch chain optimization before the final CSE/DCE pass.

Fix from
7cf4c01039:
Apply fix from Per Bothner.
In Per's words:
* testing.scm (%test-end): Reset test-runner-current if done.
This fixes bug "Loading test source file multiple time without having
report incrementing" reported to srfi-64 mailing list.
* srfi-64-test.scm: Update due to recent srfi-64 implementation change.
* module/language/cps/compile-bytecode.scm (compile-function): Expect
eq-constant? instead of eq-null?, etc.
* module/language/cps/effects-analysis.scm: Likewise.
* module/language/cps/reify-primitives.scm (reify-primitives): For
eq-constant?, reify a $const unless the constant is an immediate whose
encoding fits in 16 bits.
* module/language/cps/type-fold.scm (materialize-constant): Helper to
make a constant from a type, min, and max.
(fold-eq-constant?): New helper.
(eq-constant?): New folder.
(undefined?): Define specifically.
(define-nullish-predicate-folder): Renamd from
define-special-immediate-predicate-folder. Use only for null?, false,
and nil?.
(*branch-reducers*): New mechanism. Reduce eq? to eq-constant? if
possible.
(local-type-fold): Refactor to use materialize-constant, and to allow
reducing branches.
* module/language/cps/types.scm (constant-type): Return three values
instead of a type entry.
(constant-type-entry): New function that returns a type entry. Adapt
callers.
(infer-constant-comparison): New helper.
(eq-constant?): New inferrer.
(undefined?): New inferrer.
* module/language/tree-il/compile-bytecode.scm (eq-constant?): Fix
truncate-bits signed arg.
(define-immediate-type-predicate): Adapt to visit-immediate-tags
change.
* module/language/tree-il/compile-cps.scm (convert): Convert eq? to
constant to eq-constant?. Advantaged is that it gets fixnums and
chars in addition to special immediates.
* module/language/tree-il/cps-primitives.scm (define-immediate-type-predicate):
Adapt to allow #f as pred.
* module/system/base/types/internal.scm (immediate-tags): Use #f as pred
for false, nil, etc.
(immediate-bits->scm): Adapt.
* module/system/vm/assembler.scm (emit-eq-null?, emit-eq-nil?)
(emit-eq-false?, emit-eq-true?, emit-unspecified?, emit-eof-object?):
Remove specialized emitters.
* module/system/vm/assembler.scm (define-immediate-tag=?-macro-assembler):
Allow for pred to be #f.
* module/system/vm/disassembler.scm (define-immediate-tag-annotation):
Adapt to pred being #f.
* module/language/tree-il/compile-bytecode.scm (eq?): Define
eq-immediate? as immediate emitter.
(canonicalize): Don't fuss so much about eq?; only if commutation is
needed. (Perhaps a more generic commutation pass is needed.)
(compile-closure): Add support for emit/immediate for branches.
* module/system/base/types/internal.scm (scm->immediate-bits):
(immediate-bits->scm, sign-extend, truncate-bits): New public
routines.
* module/system/vm/assembler.scm (immediate-bits): Reimplement in terms
of scm->immediate-bits and similar.
(X8_S8_I16, X8_S8_ZI16): Rework operand encodings.
(load-constant): Use truncate-bits to determine which cases apply.
* doc/ref/vm.texi (Instruction Set, Constant Instructions): Document new
instruction.
* libguile/instructions.c (FOR_EACH_INSTRUCTION_WORD_TYPE): New first
word kind with zi16 operand.
* libguile/jit.c (compile_make_immediate, compile_make_immediate_slow):
New compilers.
(COMPILE_X8_S8_ZI16): New operand kind.
* libguile/vm-engine.c (make-immediate): New instruction.
* module/language/bytecode.scm:
* module/system/vm/assembler.scm (encode-X8_S8_ZI16<-/shuffle):
(signed-bits, load-constant): Support the new instruction kind.
* module/system/vm/disassembler.scm (disassemblers)
(sign-extended-immediate, code-annotation): Support for zi16
operands.
* lightening/lightening.c (abi_gpr_to_mem): Write whole words when
spilling GPRs to the stack. Always correct given that all Lightening
operations that write GPRs write the whole register, and the current
ABI targets allow writing the extra words. Closes#15.
