If the early pledge() call on OpenBSD fails, it calls my_errorf()
which requires the "progname" variable.

IMPORTANT: This includes a security fix to command line tool
argument handling.
Some toolchains embed an application manifest by default to declare
UAC-compliance. Some also declare compatibility with Vista/8/8.1/10/11
to let the app access features newer than those of Vista.
We want all the above but also two more things:
- Declare that the app is long path aware to support paths longer
than 259 characters (this may also require a registry change).
- Force the code page to UTF-8. This allows the command line tools
to access files whose names contain characters that don't exist
in the current legacy code page (except unpaired surrogates).
The UTF-8 code page also fixes security issues in command line
argument handling which can be exploited with malicious filenames.
See the new file w32_application.manifest.comments.txt.
Thanks to Orange Tsai and splitline from DEVCORE Research Team
for discovering this issue.
Thanks to Vijay Sarvepalli for reporting the issue to me.
Thanks to Kelvin Lee for testing with MSVC and helping with
the required build system fixes.

Now the information in the "Details" tab in the file properties
dialog matches the naming convention of Cygwin and MSYS2. This
is only a cosmetic change.

The MB output can overflow with huge numbers. Most likely these are
invalid .lzma files anyway, but let's avoid garbage output.
lzmadec was adapted from LZMA Utils. The original code with this bug
was written in 2005, over 19 years ago.

"xzdec -M123" exited with exit status 1 without printing
any messages. The "M:" entry should have been removed when
the memory usage limiter support was removed from xzdec.

Support for instruction "movzw" without suffix in "GNU as" was
added in commit [1] and stabilized in binutils 2.27, released
in August 2016. Earlier systems don't accept this instruction
without a suffix, making range_decoder.h's inline assembly
unable to build on old systems such as Ubuntu 16.04, creating
error messages like:
lzma_decoder.c: Assembler messages:
lzma_decoder.c:371: Error: no such instruction: `movzw 2(%r11),%esi'
lzma_decoder.c:373: Error: no such instruction: `movzw 4(%r11),%edi'
lzma_decoder.c:388: Error: no such instruction: `movzw 6(%r11),%edx'
lzma_decoder.c:398: Error: no such instruction: `movzw (%r11,%r14,4),%esi'
Change "movzw" to "movzwl" for compatibility.

(cherry picked from commit 6cd7c86078)
It won't be implemented. find + xargs is more flexible, for example,
it allows compressing small files in parallel. An example for that
has been included in the xz man page since 2010.

On E2K the function compiles only due to compiler emulation but the
function is never used. It's cleaner to omit the function when it's
not needed even though it's a "static inline" function.
Thanks to Ilya Kurdyukov.

GCC 4.2 doesn't have __builtin_bswap16() and friends so tuklib_integer.h
tries to use OS-specific byte swap methods instead. On OpenBSD those
macros are swap16/32/64 instead of bswap16/32/64 like on other *BSDs
and Darwin.
An alternative to "#ifdef __OpenBSD__" could be "#ifdef swap16" as it
is a macro. But since OpenBSD seems to be a special case under this
special case of "*BSDs and Darwin", checking for __OpenBSD__ seems
the more conservative choice now.
Thanks to Christian Weisgerber and Brad Smith who both submitted
the same patch a few hours apart.

Solaris' GCC can't understand that our use is fine, unlike modern compilers:
```
list.c: In function 'print_totals_basic':
list.c:1191:4: error: format not a string literal, argument types not checked [-Werror=format-nonliteral]
uint64_to_str(totals.files, 0));
^~~~~~~~~~~~~
cc1: all warnings being treated as errors
```
It's presumably because of older gettext missing format attributes.
This is with `gcc (GCC) 7.3.0`.

This is closer to what it was before the --filtersX support was added,
just extended to support for scaling all filter chains. The method
before this commit was an extended version of the original too but
it was done in a more complex way for no clear reason. In case of
an error, the complex version printed fewer informative messages
(a good thing) but it's not a sigificant benefit.
In the limit is too low even for single-threaded mode, the required
amount of memory is now reported like in 5.4.x instead of like in
5.5.1alpha - 5.6.1 which showed the original non-scaled usage. It
had been a FIXME in the old code but it's not clear what message
makes the most sense.

It's more logical to do it in the beginning instead of in the middle
of the filter chain handling.
Fixes: d6af7f3470
(cherry picked from commit 32500dfaad)
The convention is that
lzma_filter filters[LZMA_FILTERS_MAX + 1];
contains the filters of a single filter chain.
It was so here as well before the commit
d6af7f3470.
It changes "filters" to a ten-element array of filter chains.
It's clearer to call this array-of-arrays "chains".
This also renames "filter_idx" to "chain_idx" which is used
as an index as in chains[chain_idx].
(cherry picked from commit ad146b1f42)
opt_mode == MODE_COMPRESS isn't possible when HAVE_ENCODERS isn't
defined. Thus, when *encoding*, the message about *decoder* memory
usage is possible to show only when both encoder and decoder have
been built.
Since the message is shown only at V_DEBUG, skip the memusage
calculation if verbosity level isn't high enough.
