Correct the case that converting the second argument to an inexact
numbe produces an integer by losing precision.

The `(cdr tc-ptr-offsets)` in the recrusrion was wrong, but use
`thread->objects` and `thread->stack-objects` to work more generally.

Use OSSP UUID on {Free,Open}BSD and native UUID on NetBSD.
Building on OpenBSD requires a filesystem mounted with wxneeded.

@gus-massa's adjustments to the Racket test suite exposed more places
where the "primdata.ss" spec was wrong.

It fails when the argument is +inf.0, so it's not possible to make it unsafe
automatically when the argument is a number.

- zero?, fxzero?, positive?, fxpositive?, etc., now go through
(a suitably modified) relop-length so that, for example,
(zero? (length x)) results in the same code as (null? x). added
correctness tests for these and all of the other predicates that
go through relop-length.
cpnanopass.ss, 5_2.ms
- assertion-violationf and friends now show the who, message, and
irritants in the original call when who or message is found not to
be of the right type.

In expressions like

the reduction was dropping the possible side effect expressions
in this case the (newline).

- added compress-level parameter to select a compression level for
file writing and changed the default for lz4 compression to do a
better job compressing. finished splitting glz input routines
apart from glz output routines and did a bit of other restructuring.
removed gzxfile struct-as-bytevector wrapper and moved its fd
into glzFile. moved DEACTIVATE to before glzdopen_input calls
in S_new_open_input_fd and S_compress_input_fd, since glzdopen_input
reads from the file and could block. the compress format and now
level are now recorded directly the thread context. replaced
as-gz? flag bit in compressed bytevector header word with a small
number of bits recording the compression format at the bottom of
the header word. flushed a couple of bytevector compression mats
that depended on the old representation. (these last few changes
should make adding new compression formats easier.) added
s-directory build options to choose whether to compress and, if
so, the format and level.

- improved the effectiveness of LZ4 boot-file compression to within
15% of gzip by increasing the lz4 output-port in_buffer size to
1<<18. With the previous size (1<<14) LZ4-compressed boot files
were about 50% larger. set the lz4 input-port in_buffer and
out_buffer sizes to 1<<12 and 1<<14. there's no clear win at
present for larger input-port buffer sizes.
compress-io.c
- To reduce the memory hit for the increased output-port in_buffer
size and the corresponding increase in computed out_buffer size,
one output-side out_buffer is now allocated (lazily) per thread
and stored in the thread context. The other buffers are now
directly a part of the lz4File_out and lz4File_in structures
rather than allocated separately.
compress-io.c, scheme.c, gc.c,
cmacros.ss
- split out the buffer emit code from glzwrite_lz4 into a
separate glzemit_lz4 helper that is now also used by gzclose
so we can avoid dealing with a NULL buffer in glzwrite_lz4.
glzwrite_lz4 also uses it to writing large buffers directly and
avoid the memcpy.
compress-io.c
- replaced lz4File_out and lz4File_in mode enumeration with the
compress format and inputp boolean. using switch to check and
raising exceptions for unexpected values to further simplify
adding new compression formats in the future.
compress-io.c
- replaced the never-defined struct lz4File pointer in glzFile
union with the more specific struct lz4File_in_r and Lz4File_out_r
pointers.
compress-io.h, compress-io.c
- added free of lz4 structures to gzclose. also changed file-close
logic generally so that (1) port is marked closed before anything is
freed to avoid dangling pointers in the case of an interrupt or
error, and (2) structures are freed even in the case of a write
or close error, before the error is reported. also now mallocing
glz and lz4 structures after possibility of errors have passed where
possible and freeing them when not.
compress-io.c,
io.ss
- added return-value checks to malloc calls and to a couple of other
C-library calls.
compress-io.c
- corrected EINTR checks to look at errno rather than return codes.
compress-io.c
- added S_ prefixes to the glz* exports
externs.h, compress-io.c, new-io.c, scheme.c, fasl.c
- added entries for mutex-name and mutex-thread

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.
