a70e96d2da CMake: Fix time.h checks not running on second CMake run.
If CMake was configured more than once, HAVE_CLOCK_GETTIME and
HAVE_CLOCK_MONOTONIC would not be set as compile definitions. The check
for librt being needed to provide HAVE_CLOCK_GETTIME was also
simplified.

d5275d83bd CMake: Fix unconditionally defining HAVE_CLOCK_MONOTONIC.
If HAVE_CLOCK_GETTIME was defined, then HAVE_CLOCK_MONOTONIC was always
added as a compile definition even if the check for it failed.

1f6e7c68fb xz: Refactor thousand separator detection and disable it on MSVC.
Now the two variations of the format strings are created with
a macro, and the whole detection code can be easily disabled
on platforms where thousand separator formatting is known to
not work (MSVC has no support, and on DJGPP 2.05 it can have
problems in some cases).

ef71f83973 xz: Fix a too relaxed assertion and remove uses of SSIZE_MAX.
SSIZE_MAX isn't readily available on MSVC. Removing it means
that there is one thing less to worry when porting to MSVC.

773f1e8622 liblzma: Update assert in vli_ceil4().
The argument to vli_ceil4() should always guarantee the return value
is also a valid lzma_vli. Thus the highest three valid lzma_vli values
are invalid arguments. All uses of the function ensure this so the
assert is updated to match this.

68bda971bb liblzma: Add overflow check for Unpadded size in lzma_index_append().
This was not a security bug since there was no path to overflow
UINT64_MAX in lzma_index_append() or when it calls index_file_size().
The bug was discovered by a failing assert() in vli_ceil4() when called
from index_file_size() when unpadded_sum (the sum of the compressed size
of current Stream and the unpadded_size parameter) exceeds LZMA_VLI_MAX.

Previously, the unpadded_size parameter was checked to be not greater
than UNPADDED_SIZE_MAX, but no check was done once compressed_base was
added.

This could not have caused an integer overflow in index_file_size() when
called by lzma_index_append(). The calculation for file_size breaks down
into the sum of:

- Compressed base from all previous Streams
- 2 * LZMA_STREAM_HEADER_SIZE (size of the current Streams header and
  footer)
- stream_padding (can be set by lzma_index_stream_padding())
- Compressed base from the current Stream
- Unpadded size (parameter to lzma_index_append())

The sum of everything except for Unpadded size must be less than
LZMA_VLI_MAX. This is guarenteed by overflow checks in the functions
that can set these values including lzma_index_stream_padding(),
lzma_index_append(), and lzma_index_cat(). The maximum value for
Unpadded size is enforced by lzma_index_append() to be less than or
equal UNPADDED_SIZE_MAX. Thus, the sum cannot exceed UINT64_MAX since
LZMA_VLI_MAX is half of UINT64_MAX.

Thanks to Joona Kannisto for reporting this.

6614e6d4bf Docs: Update INSTALL for --enable-threads method win95.

e919ebb29a Build: Conditionally allow win95 threads and --enable-small.
When the compiler supports __attribute__((__constructor__))
mythread_once() is never used, even with --enable-small. A configuration
with win95 threads and --enable-small will compile and be thread safe so
it can be allowed.

This isn't a very common configuration since MSVC does not support
__attribute__((__constructor__)), but MINGW32 and CLANG32 environments
for MSYS2 can use win95 threads and have
__attribute__((__constructor__)) support.

c0c0cd4a48 mythread.h: Fix typo error in Vista threads mythread_once().
The "once_" variable was accidentally referred to as just "once". This

6a1093c000 build-aux/manconv.sh: Fix US-ASCII and UTF-8 output.
groff defaults to SGR escapes. Using -P-c passes -c to grotty
which restores the old behavior. Perhaps there is a better way to
get pure plain text output but this works for now.

4170a80785 mythread.h: Disable signal functions in builds targeting Wasm + WASI.
signal.h in WASI SDK doesn't currently provide sigprocmask()
or sigset_t. liblzma doesn't need them so this change makes
liblzma and xzdec build against WASI SDK. xz doesn't build yet
and the tests don't either as tuktest needs setjmp() which
isn't (yet?) implemented in WASI SDK.

962b3d41e0 CMake: Conditionally allow the creation of broken symlinks.
The CMake build will try to create broken symlinks on Unix and Unix-like
platforms. Cygwin and MSYS2 are Unix-like, but may not be able to create
broken symlinks. The value of the CYGWIN or MSYS environment variables
determine if broken symlinks are valid.

The default for MSYS2 does not allow for broken symlinks, so the CMake
build has been broken for MSYS2 since commit
80a1a8bb83.

19899340cf liblzma: Prevent an empty translation unit in Windows builds.
To workaround Automake lacking Windows resource compiler support, an
empty source file is compiled to overwrite the resource files for static
library builds. Translation units without an external declaration are
not allowed by the C standard and result in a warning when used with
-Wempty-translation-unit (Clang) or -pedantic (GCC).

more clear that the options listed are the ones relevant for
encoding or decoding.
