p is a pointer that iterates over path, which is buffer.
We should not try to get to an address preceding its start.
Since there was an execution path that leads to that,
guard against it with an additional check.

Previously it was using #!/bin/bash as its interpreter. It is not
compatible with FreeBSD because bash is not installed by default.
The update-revision script is #!/bin/sh compatible and there are
other examples of #!/bin/sh scripts in the codebase so the change
is consistent with them.

- 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.

In expressions like
(record-ref ... (begin (newline) (record ...)))
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,

- 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

original commit: 722ffabef4c938bc92c0fe07f789a9ba350dc6c6
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.

Mf-install.in
- improved packaging support:
replaced bintar script with bintar directory and make file;
tarballs are created via "make create-tarball" and are placed in
the workarea's bintar directory. added rpm directory and make
file for creating RPMs via "make create-rpm". added pkg directory
and make file for creating OSX packages via "make create-pkg".

original commit: fdff97d15cd827eb8fbef200c0f495a4bfaefff3
added fix for whole program/library compilation bug with help from
@owaddell who originally reported the problem in issue 386. this bug
arises from the way the parts of the combined library, and their
binary dependencies, are invoked when one of the constituent libraries
is invoked. consider, for example, a combined library that contains
(A) and (B), where (B) depends on a binary library (C). depending on
the sort order of (A) and (B), which may be unconstrained in the
partial ordering established by library dependencies, invoking (A) may
result in the invoke code for (B) being run first, without (B) ever
being explicitly invoked. this can result in bindings required from
(C) by the invoke code in (B) to be unbound. even in the case where
(A) comes before (B) in the topological sort, if they are combined
into the same cluster, (B)'s invoke code will be run as part of
invoking (A). the solution is two part: first we extend the invoke
requirements of the first library in the cluster to include the binary
libraries that precede it in the topological sort and add a dependency
on the first library in the cluster to all of the other libraries in
the cluster. this means no matter which library in the cluster is
invoked first, it will cause the first library to be invoked, in turn
ensuring the binary libraries that precede it are invoked. when there
are multiple clusters, a dependency is added from each cluster to the
first library in the cluster that precedes it. this ensures that
invoking a library in a later cluster first, will still cause all of
the dependencies of the previous clusters to be invoked. ultimately,
these extra dependencies enforce an ordering on the invocation of the
source and binary libraries that matches the topological sort, even if
the topological sort was under constrained. to maintain the property
that import requirements are a superset of the invoke and visit
requirements, we also extend the import requirements to include the
extended invoke requirements. the import requirements are also added
to the dependency graph to further constrain the topological sort and
ensure that we do not introduce artificial cycles in the import graph.
