add name fields for mutexes and condition variables, now `make-mutex` and `make-condition` accept an optional argument `name`, which must be a symbol or #f. The name, if not #f, is printed every time the object is printed, which is useful for debugging.

- fixed handling of bintar, rpm, pkg make files
newrelease
- fixed a bug in the fasl representation and reading of mutually
recursive ftypes where one of the members of the cycle is the
parent of another, which manifested in the fasl reader raising
bogus "incompatible record type" exceptions. (The bug could also
affect other record-type descriptors with cycles involving parent
rtds and "extra" fields.) object files created before this fix
are incompatible with builds with this fix, and objects files
created after this fix are incompatible builds without this fix.

packaging to the release notes.

controversial, unless I damaged something in the process of integrating
them with other recent changes. the user's guide and release notes
have been updated as well to reflect the changes of interest to end
users.
- the body of load-library is now wrapped in a $pass-time with
to show the time spent loading libraries separately from the time
spent in expand.
syntax.ss
- interpret now plays the pass-time game
interpret.ss
- added compile-time-value? predicate and
compile-time-value-value accessor
syntax.ss, primdata.ss,
8.ms, primvars.ms, root-experr*
- $pass-stats now returns accurrate stats for the currently timed
pass.
7.ss
- compile-whole-program and compile-whole-library now propagate
recompile info from the named wpo file to the object file
to support maybe-compile-program and maybe-compile-library in
the case where compile-whole-{program,library} overwrites the
original object file.
compile.ss,
7.ms, mat.ss, primvars.ms
- replaced the ancient and unusable bintar with one that creates
a useful tarball for binary installs
bintar
- generated Mf-install InstallBin (InstallLib, InstallMan) now
correctly indirects through InstallPrefix if the --installbin
(--installlib, --installman) configure flag is not present.
src/configure
- removed definition of generate-procedure-source-information
patch.ss
- guardian tconc cells are now allocated in generation 0 in the hope
that they can be released more quickly.
gc.c
- added ftype-guardian syntax: (ftype-guardian A) creates a new
guardian for ftype pointers of type A, the first base field (or
one of the first base fields in the case of unions) of which must
be a word-sized integer with native endianness representing a
reference count. ftype pointers are registered with and retrieved
from the guardian just like objects are registered with and
retrieved from any guardian. the difference is that the garbage
collector decrements the reference count before resurrecting an
ftype pointer and resurrects only those whose reference counts
become zero, i.e., are ready for deallocation.

- fixed a bug in automatic recompilation handling of missing include
files specified with absolute pathnames or pathnames starting with
"./" or "..": was erroring out in file-modification-time with a
file-not-found or other exception rather than recompiling.
syntax.ss,
7.ms, root-experr*, patch*
- changed inline vector-for-each and string-for-each code to
put the last call to the procedure in tail position, as was
already done for the library definitions and for the inline
code for for-each.
cp0.ss,
5_4.ms, 5_6.ms
- the compiler now generates better inline code for the bytevector
procedure. instead of one byte memory write for each argument,
it writes up to 4 (32-bit machines) or 8 (64-bit machines) bytes
at a time, which almost always results in fewer instructions and
fewer writes.
cpnanopass.ss,
bytevector.ms
- packaged unchanging implicit reader arguments into a single record
to reduce the number of arguments.
read.ss
- recoded run-vector to handle zero-length vectors. it appears
we're not presently generating empty vectors (representing empty
groups), but the fasl format permits them.
7.ss
original commit: 7be1d190de7171f74a1ee71e348d3e6310392686
- fixed a bug in which instantiating a static foreign-callable code object
fails with an invalid memory reference because the collector has
discarded its relocation information. foreign-callable code objects
are now flagged as "templates", and the collector now refuses to
discard relocation information for code objects marked as templates
when copying them to the static generation.
cmacros.ss, cpnanopass.ss,
gc.c,

- committing updated boot/*/equates.h (without the boot files, which are
still usable for bootstrapping)
boot/*/*.h
- updated release notes

fix#389 (apply doesn't throw exception when last argument isn't a list)
fold-primref and fold-primref2 ignored app-convention when
attempting to fold certain primitive calls in 'test and 'effect
context and when falling back on the default primitive handler.
We now residualize primitive references if the app-convention
is not 'call. The original fold-primref2 already bypassed the
inline handler when the app-convention was not 'call.

Also adds `get-initial-thread`, since threa values are useful with
`compute-size[-increments]`.
Changes the compiler to inline `weak-pair?` and `ephemeron-pair?`,
since that provides better performance for `compute-size-increments`.
original commit: 57d0cc13f8e932972cba3837b4f54e9c86786091
- the compiler now uses a temporary variable to hold the return
value of a nested call across the restore-local-saves form to
properly handle the case where the destination lvalue is an mref
whose base and/or index is a local save.

A program can use `make-arity-wrapper-procedure` to synthesize a
function that reports a given arity mask (without calling `compile`).
In addition, `set-arity-wrapper-procedure!` suports modifying the
implementation of a synthesized procedure. Although similar
functionality could be achieved with `(lambda args (apply (unbox proc)
args))`, an arity wrapper procedure can dispatch to another procedure
without allocating a list for the arguments.
The interpreter now uses an internal variant of arity wrappers to
cooperate with `procedure-arity-mask`.
original commit: 5fede14302840b55edbeb7565e28d09350a4b2e9
- fixed an issue with the library system where an exception that occurs
during visit or revisit left the library in an inconsistent state that
caused it to appear that it was still in the process of running. This
manifested in it raising a cyclic dependency exception, even though
there really is not a cyclic dependency. The various library
management functions involved will now reset the part of the library
when an exception occurs. This also means that if the library visit
or revisit failed for a transient reason (such as a missing or
incorrect library version that can be fixed by updating the
library-directories) it is now possible to recover from these errors.

Also, report an error if a string type is misused as an argument (for
foreign procedures) or result (for foreign callables) with
`__collect_safe`.
