8fd3ac046d Don't set lc=4 with --extreme.
This should reduce the cases where --extreme makes
compression worse. On the other hand, some other
files may now benefit slightly less from --extreme.

373ee26f95 Adjust memory limits in test_compress.sh
Testing compression at level -4 now requires 48 MiB of free store at
compression time and 5 MiB at decompression time.

b4b1cbcb53 Tweak the compression presets -0 .. -5.
"Extreme" mode might need some further tweaking still.

77fe5954cd liblzma: Adjust default depth calculation for HC3 and HC4.
It was 8 + nice_len / 4, now it is 4 + nice_len / 4.
This allows faster settings at lower nice_len values,
even though it seems that I won't use automatic depth
calcuation with HC3 and HC4 in the presets.

fce69059cf xz: Make --help two lines shorter.
At least for now, the --help option doesn't list any
options that take arguments, so "Mandatory arguments to..."
can be omitted.

a848e47ced xz: Make setting a preset override a custom filter chain.
This is more logical behavior than ignoring preset level
options once a custom filter chain has been specified.

d5653ba8a1 Fix test_compress.sh.
It broke when --memory option was removed from xzdec.

Thanks to Jonathan Nieder.

792331bdee Disable the memory usage limiter by default.
For several people, the limiter causes bigger problems that
it solves, so it is better to have it disabled by default.
Those who want to have a limiter by default need to enable
it via the environment variable XZ_DEFAULTS.

Support for environment variable XZ_DEFAULTS was added. It is
parsed before XZ_OPT and technically identical with it. The
intended uses differ quite a bit though; see the man page.

The memory usage limit can now be set separately for
compression and decompression using --memlimit-compress and
--memlimit-decompress. To set both at once, -M or --memlimit
can be used. --memory was retained as a legacy alias for
--memlimit for backwards compatibility.

The semantics of --info-memory were changed in backwards
incompatible way. Compatibility wasn't meaningful due to
changes in the memory usage limiter functionality.

The memory usage limiter info is no longer shown at the
bottom of xz --long -help.

The memory usage limiter support for removed completely from xzdec.

xz's man page was updated to match the above changes. Various
unrelated fixes were also made to the man page.

bab0f01ed9 Add two simple example programs.
Hopefully these help a bit when learning the basics
of liblzma API. I plan to write detailed examples about
both basic and advanced features with lots of comments,
but these two examples are good have right now.

The examples were written by Daniel Mealha Cabrita. Thanks.

b5fbab6123 Silence a bogus Valgrind warning.
When using -O2 with GCC, it liked to swap two comparisons
in one "if" statement. It's otherwise fine except that
the latter part, which is seemingly never executed, got
executed (nothing wrong with that) and then triggered
warning in Valgrind about conditional jump depending on
uninitialized variable. A few people find this annoying
so do things a bit differently to avoid the warning.

d8a55c48b3 Remove the Subblock filter code for now.
The spec isn't finished and the code didn't compile anymore.
It won't be included in XZ Utils 5.0.0. It's easy to get it
back once the spec is done.

b6377fc990 Split message_filters().
message_filters_to_str() converts the filter chain to
a string. message_filters_show() replaces the original
message_filters().

uint32_to_optstr() was also added to show the dictionary
size in nicer format when possible.

6548e30465 Updates to tuklib_physmem and tuklib_cpucores.
Don't use #error to generate compile error, because some
compilers actually don't take it as an error. This fixes
tuklib_physmem on IRIX.

Fix incorrect error check for sysconf() return values.

Add AIX, HP-UX, and Tru64 specific code to detect the
amount RAM.

Add HP-UX specific code to detect the number of CPU cores.

Thanks a lot to Peter O'Gorman for initial patches,
testing, and debugging these fixes.
