Depending on header search path ordering, we can easily
confuse libarchive_fe/err.h with the system header.
Rename ours to lafe_err.h to avoid the confusion.
Rename libarchive_fe/err.c to match.
Ignoring SIGCHLD gets passed to child processes. Doing that has
influence on waitpid, namely that zombie processes won't be
created. This means that a status can never be read.
We can't enforce this in library, but libarchive's tools can be
protected against this by enforcing default handling.

The cygwin FAQ states that __CYGWIN__ is defined when building for a
Cygwin environment. Only a few test files check (inconsistently) for
CYGWIN, so adjust them to the recommended __CYGWIN__ definition.

`Int32x32To64` macro internally truncates the arguments to int32, while
`time_t` is 64-bit on most/all modern platforms. Therefore, usage of
this macro creates a Year 2038 bug.
I detailed this issue a while ago in a writeup, and spotted the same
issue in this repository when updating the list of affected
repositories:
<https://cookieplmonster.github.io/2022/02/17/year-2038-problem/>
A few more notes:
1. I changed all uses of `Int32x32To64` en masse, even though at least
one of them was technically OK and used with int32 parameters only. IMO
better safe than sorry.
2. This is untested, but it's a small enough change that I hope the CI
success is a good enough indicator.
This plumbing is required for cmake/ctest to recognise and report
skipped tests.
Now skipped tests in cmake ci jobs are reported like so:
```
Start 7: libarchive_test_acl_platform_posix1e_read
7/785 Test #7: libarchive_test_acl_platform_posix1e_read ................................***Skipped 0.02 sec
```
And there is a list of skipped tests shown at the end of the test run.
This is the first part of converting the project to use SPDX license
identifiers instead using the verbose license text.
The patches are semi-automated and I've went through manually to ensure
no license changes were made. That said, I would welcome another pair of
eyes, since I am only human.

This fixes various code quality issues I encountered while chasing a
memory leak reported by test automation. I failed to reproduce the
memory leak, but I hope you find this useful nonetheless.
In order to match cpio output, format the reference date with _at least_
12 bytes instead of _exactly_ 12 bytes. This should fix a gratuitous
test failure on certain systems that default to multi-byte locales.
Fixes all test-related compiler warnings with Visual Studio 2022 on
Windows 11.

Supplying a lot of "-" arguments to tools can lead to stack overflow due
to recursive *_getopt function calls.
Proof of Concept:
1. Compile libarchive with Visual Studio 2022
2. Call bsdtar with insane amount of arguments
```
PS> bsdtar.exe ("- "*10000).split(" ")
```
The event log shows that bsdtar.exe failed with `0xc00000fd` (stack
overflow).
If compiled with gcc, this does not happen by default because the code
is internally optimized to use this suggested loop instead. You have to
compile with CFLAGS="-O0" to provoke it with gcc as well.
Earlier MR https://github.com/libarchive/libarchive/pull/2000 forgot to
annotate some functions as __LA_NORETURN. While fixing that I've noticed
that the bsdcat.h header could use some fixes so I've snuck those in.
Kind of make sense to group in one PR, but can split people prefer so.

The libarchive source tree is littered with `__FBSDID("$FreeBSD.*")` and
'$FreeBSD$' tags left over from extracting it from FreeBSD's Subversion
repo. They never made sense for a git repo as git doesn't expand them
and FreeBSD has now removed `$FreeBSD$` from most local source files so
these stand out.
In addition to `__FBSDID` I've removed `__RCSID` which was used once for
a `$NetBSD$` expansion. There might be more of a case to be made for
preserving this one as a diff-reduction measure, but it seems mostly
pointless.
This builds and tests pass except for
libarchive_test_read_disk_directory_traversals which failed on master as
well.
CreateFileW is not allowed in Universal Windows Platform (UWP) builds but
CreateFile2 is available. We could just enable this code for UWP but
it's probably to use it going forward so the code is properly tested on
both sides.
Without this patch, `bsdcpio_test_option_c` failed after 2038-01-19 with
```
.../libarchive-3.6.2/cpio/test/test_option_c.c:143: Assertion failed: t >= now - 2
.../libarchive-3.6.2/cpio/test/test_option_c.c:169: Assertion failed: t >= now - 2
.../libarchive-3.6.2/cpio/test/test_option_c.c:205: Assertion failed: t >= now - 2
```
Background:
As part of my work on reproducible builds for openSUSE, I check that
software still gives identical build results in the future.
The usual offset is +16 years, because that is how long I expect some
software will be used in some places.
This showed up failing tests in our package build.
See https://reproducible-builds.org/ for why this matters.
Otherwise there are 32/64-bit pointer conversions going on. In Windows
since MSVC2005, time_t has been 64-bit. MinGW needs a hack to get 64-bit
time_t.
