Choose the ragged stop strategy when the GC kind is determined, so that
we do so with respect to a single measurement of pending unavailable
bytes.
Also remove assert in heap_should_mark_while_stopping, as it can be
called after stopping too, when evacuation is enabled.
The counters are unsigned, so that they can overflow. (Is that really
necessary though?) In any case try_pop can decrement a counter, leading
to a situation where you can think you have (size_t)-1 elements; not
good. Instead when computing the queue size, use a signed value.
Limits total queue size to half the unsigned space; fine.
On MinGW, 'system' uses a non-posix shell that does not handle
apostrophe as a quoting character. For this test, quoting a command-line
with double quotes allows it to be run with both /bin/sh and cmd.exe.
* test-suite/tests/c-api.test (egrep): use double quotes when
quoting command line
The standalone egrep script has been deprecated by GNU grep.
'grep -E' is the suggested replacement.
* test-suite/tests/c-api.test (egrep): replace egrep with grep -E
* module/srfi/srfi-35.scm (condition): Use 'make-exception' instead of
'make-compound-condition', which is unbound in this module.
* test-suite/tests/srfi-35.test ("syntax")["compound condition,
hygienic macro expansion"]: New test.
* doc/ref/sxml.texi (7.21.4 Transforming SXML): Adds a mention to the
module to be imported for the procedures introduced in this section of
the documentation..

Avoids spurious "error in finalization thread: Success" messages when
the finalization pipe gets closed.
* libguile/finalizers.c (finalization_thread_proc): Return when 'data.n'
is zero.
MinGW ACL-based permissions don't follow POSIX standard, so
'chmod' has unexpected behavior.
* test-suite/tests/ftw.test (mingw?): new define
("file system fold: EACCES"): skip test on MinGW
This is the same strategy as used for the 'accept4' bindings introduced
in 6e0965104c.
* libguile/posix.c (scm_pipe): Rename to...
(scm_pipe2): ... this. Add an optional 'flags' parameter and honor it.
(scm_pipe): Rewrite as a call to 'scm_pipe2'.
* libguile/posix.h (scm_pipe2): New declaration.
* test-suite/tests/posix.test ("pipe"): New tests.
* configure.ac: Look for 'pipe2'.
* NEWS: Update.
This makes the docstring attached to the curried function being defined
rather than the result of its application until a function that runs the
body is obtained, fixing

Locations are stored in tree-il records in "source vector" form, but
`location-string' was rendering these as <unknown-location>.
* module/system/base/message.scm (location-string): Support locations
passed as a file/line/column vector.
We don't need a pin bit: we just need to mark pinned objects before
evacuation starts. This way we can remove the stopping / marking race
so that we can always mark while stopping.
The collector now has an abstract interface onto the embedder. The
embedder has to supply some functionality, such as tracing and
forwarding. This is a pretty big change in terms of lines but it's
supposed to have no functional or performance change.
We're targetting systems that need to be able to inspect the kind of an
object, so this information has to be somewhere. If it's out-of-line,
we might save memory, but we would lose locality. Concretely in Guile
the tag bits are in the object itself.
