I tested FreeBSD, DragonflyBSD, NetBSD and OpenBSD and the endian
macros weren't necessary (and in fact caused errors) on all of them.
Because OpenBSD ships with an ancient GCC that doesn't support the
checked addition/multiplication builtins, the build there would fail
unless built with CC=cc or CC=clang. I changed configure.ac to prefer
cc over gcc, so that the distribution's compiler preference is
respected. (The default is [gcc cc]). I had to move AC_PROG_CC above
LT_INIT because otherwise LT_INIT would run AC_PROG_CC first, and we
wouldn't have a chance to use non-default parameters.

"Some" "non-POSIX systems" don't have that.

Set an automake variable and force --without-tools by default. Also,
don't even try to check for pthread if we are compiling for Windows.

If this option is used, only libsquashfs is built and installed,
and the test cases for the other helper libraries are deactivated.

Instead of defaulting to -j 1 and -Q 10 times the job count if no option is
provided, let tar2sqfs and gensquashfs use all available CPUs and about
roughly half the available RAM, if this information can be gathered.

This commit modifies the build system to optionally generate a
reference manual for libsquashfs using Doxygen (if Doxygen is
available and the manual is explicitly built).

This of course entails turning the entire project over to libtool magic.

It is optimized to the maximum and if we already use zlib anyway,
why not use zlib crc32? This also makes zlib a hard dependency which
also means the whole "do we have a compressor" sanity check in the
build system can be removed.

struct stat uses time_t to store time values. On some 32 bit systems,
this may be a 32 bit integer.
This patch adds a broken-out 64 bit time value to tar_header_decoded_t
and makes sure to clamp the value to +/- (2^32 - 1) if required when
writing it back to a struct stat.

Requires that config.h be included before other headers, since the macro
_FILE_OFFSET_BITS changes the definitions of things like 'struct stat'.
I chose to simply include it at the top of every C file and at
immediately after the double-inclusion guards of every header.

Always try to gather all compressor libraries available, but only
complain about missing a one if it has been *explicitly* selected.
If a compressor has been explicityl disabled, we can still turn it
off after checking.
Also, rework gensquashfs to set the default compressor based on
what's available.

Stick to the terminology that SquashFS uses. SquashFS uses "lzma" to
refere to lzma1, "xz" to refere to lzma2 and confusingly "gzip" to
refere to raw zlib deflate. We can avoid a lot of confusion by
_consistently_ using the same terminology.
