Port upstream LibArchive commit "compute string pointers after
concatenation" (2014-09-25) and commit "Move variables to top of
function for non-C99 compilers" (2014-11-15) to our CMake copy.
Otherwise we may compute a pointer to memory that is about to be freed
and then compute a bad size to give to CryptGenRandom.

Newer HP-UX versions (e.g. 11.31) also offers F_SETTIMES, but with a different
struct for the timing information.

In libarchive/archive_write_set_format_zip.c there are two calls to
archive_le32enc whose second argument is of the form
archive_entry_mode(zip->entry) << 16
However, the return type from archive_entry_mode may be a signed integer
so the shift may overflow. Since the second argument of archive_le32enc
expects uint32_t anyway, simply cast to that prior to shifting.
In archive_entry.h refer to "BY_HANDLE_FILE_INFORMATION *" using
"struct _BY_HANDLE_FILE_INFORMATION *" to avoid requiring the
includer to already have <windows.h>.
Resolve conflicts in favor of the upstream side where possible.
Resolve a logical conflict in archive_windows.h where the upstream
port to Watcom was done slightly differently from ours.
Port upstream commit 6cf33c93 (Issue 320: Rewrite (again) to avoid

Follow up change from commit ffa6faa4 (libarchive: Include cm_zlib.h to
get zlib used by CMake, 2011-12-20) for new includes of zlib.h in
updated libarchive.
The archive_string_conv type sc variable already freed via free(sc) on
the other hand in second line we are tyring to free its subset via
free(sc->from_charset) this will cause a problem because we couldn't
reach sc after first release.

caught by clang's -fsanitize=shift. A small unsigned int was
promoted, according to C's regular promotion rules, to a signed
int, it was then left shifted. This sometimes pushed a 1 into
the sign bit, which is undefined behaviour. Fixed by using
unsigned temporaries.
The CMake TarTest fails with the error
mbsnrtowcs.c:116: __mbsnrtowcs: Assertion
`status == GCONV_OK || status != GCONV_EMPTY_INPUT ||
status == GCONV_ILLEGAL_INPUT || status == GCONV_INCOMPLETE_INPUT ||
status == GCONV_FULL_OUTPUT' failed.
on very old glibc versions. Work around the problem by pretending that
mbsnrtowcs does not exist. Libarchive will fall back to mbrtowc.
Use the approach originally used in commit f91b3c1d (Add options to
build with system utility libraries, 2006-10-19) for all other
third-party libraries. Create a "cm_bzlib.h" header wrapper that
robustly includes the header from the bzip2 library chosen for the CMake
build (either builtin or system version). Include the header wrapper
anywhere we need the API provided by <bzlib.h>.
We cannot suppress PGI compiler warnings completely because even with
the "-w" flag the compiler still writes a message containing "compilation
completed with warnings" to stderr.
A warning is triggered by expressions like
test ? NULL : ptr_to_const_char
test ? ".." : ptr_to_const_char
that the PGI compiler handles incorrectly. It chooses the pointer type
of the first option (either void* or char*) and warns about conversion
of the second without a cast. Flip the expression logic to
!test ? ptr_to_const_char : NULL
!test ? ptr_to_const_char : ".."
to help the compiler choose the proper result type.
Configure the result as definition HAVE_STRUCT_STATVFS_F_IOSIZE and use
the member only if it exists. At least one platform (IRIX) provides
struct statvfs without this member.
VS 6 warns verbosely when WINVER >= 0x0500. Avoid defining WINVER and
_WIN32_WINNT to higher than 0x0400 on VS 6. Provide missing API
declarations in archive_windows.h when we do not get them from
<windows.h>. Provide GetVolumePathNameW because VS 6 does not declare
it regardless of the API version.
At least one compiler (Borland) defines mode_t as just "short" which is
signed. This breaks code like
switch(archive_entry_filetype(e)) {
case AE_IFREG:
...
}
if AE_IFREG and other constants have a longer signed type (int) because
sign extension of the mode_t return type from archive_entry_filetype
changes its value. Avoid the problem by ensuring the type of the
constants matches mode_t.
This change was originally made in commit a73acfbe (Fix for mode_t with
signed types, 2009-11-07). Port it to the new libarchive snapshot.
Mangle the open_FILE symbols to avoid conflict with open_file:
Warning: public '_archive_read_open_file'
in module 'archive_read_open_filename.c' clashes with
prior module 'archive_read_open_file.c'
Warning: public '_archive_write_open_file'
in module 'archive_write_open_filename.c' clashes with
prior module 'archive_write_open_file.c'
This workaround should not go upstream because it will break when
mixing compilers.
