In the past this wasn't done before releases; the Git repository
just contained the files from the Translation Project. But this
way it is clearer when comparing release tarballs against the
Git repository. In future releases this might no longer be necessary
within a stable branch as the .po files won't change so easily anymore
when creating a tarball.
When po/xz.pot doesn't exist, running "make" or "make dist" will
create it. Then the .po files will be updated but only if they
actually would change more than the POT-Creation-Date line.
Then the .gmo files would be generated from the .po files.
This is the case before and after this commit.
However, "make dist" and thus "make mydist" did a forced update
to the files, updating them even if the only change was the
POT-Creation-Date line. This had pros and cons: It made it clear
that the .po file really is in sync with the recent strings in
the package. On the other hand, it added noise in form of changed
files in the source tree and distribution tarballs. It can be
ignored with something like "diff -I'^"POT-Creation-Date: '" but
it's still a minor annoyance *if* there's not enough value in
having the most recent timestamp.
Setting DIST_DEPENDS_ON_UPDATE_PO = no means that such forced
update won't happen in "make dist" anymore. However, the "mydist"
target will use xz.pot-update target which is the same target that
is run when xz.pot doesn't exist at all yet. Thus "mydist" will
ensure that the translations are up to date, without noise from
changes that would affect only the POT-Creation-Date line.
Note that po4a always uses msgmerge with --update, so POT-Creation-Date
in the man page translations is never the only change in .po files.
In that sense this commit makes the message translations behave more
similarly to the man page translations.
Distribution tarballs will still have non-reproducible POT-Creation-Date
in po/xz.pot and po4a/xz-man.pot but those are just two files. Even they
could be made reproducible from a Git timestamp if desired.

The .po files from the Translation Project come with unwrapped
strings so this matches it.
This may reduce the noise in diffs too. When the beginning of
a paragraph had changed, the rest of the lines got rewrapped
in msgsid. Now it's just one very long line that changes when
a paragraph has been edited.
The --add-location=file option was removed as redundant. The line
numbers don't exist in the .pot file due to --porefs file and thus
they cannot get copied to the .po files either.
(cherry picked from commit 4beba1cd62)
This way the PO file diffs are less noisy but the locations of the
strings are still present at file level, just without line numbers.
The option is available since gettext 0.19 (2014).
configure.ac requires 0.19.6.

Since the source strings have changed, these would get marked as
fuzzy and the original string would be used instead. The original
and translated strings are identical in this case so it wouldn't
matter. But patching the translations helps still because then
po4a will show the correct translation percentage.

One has to pass -DENABLE_X86_ASM=ON to cmake to enable the
CRC assembly code. Autodetection isn't done. Looking at
CMAKE_SYSTEM_PROCESSOR might not work as it comes from uname
unless cross-compilation is done using a CMake toolchain file.
On top of this, if the code is run on modern processors that support
the CLMUL instruction, then the C code should be faster (but then
one should also be using a x86-64 build if possible).
(cherry picked from commit 24387c234b)
The po4a directory is in EXTRA_DIST and thus all files there
are included in the package. .gitignore doesn't belong in the
package so keep that file out of the po4a directory.

Add a new optional argument to specify the directory of the xz and
xzdec executables.
If ../config.h doesn't exist, assume that all encoders and decoders
are available.
(cherry picked from commit a7e9230af9)
Add a new optional second argument: directory of the xz and xzdec
executables. This is need with the CMake build where the binaries
end up in the top-level build directory.
If ../config.h doesn't exist, assume that all encoders and decoders
are available. This will make this script usable from CMake in the
most common build configuration.
NOTE: Since the existence of ../config.h is checked, the working
directory of the test script must be a subdir in the build tree!
Otherwise ../config.h would look outside the build tree.
Use the default check type instead of forcing CRC32 or CRC64.
Now the script doesn't need to check if CRC64 is available.
(cherry picked from commit ac3222d2cb)
This is a bit hacky since the scripts grep config.h to know which
features were built but the CMake build doesn't create config.h.
So instead those test scripts will be run only when all relevant
features have been enabled.
(cherry picked from commit 006040b29c)
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].
