d4f659e12a Drop the one line short description on sources
Some are outdated, misleading or just repeat the same thing over and
over. Remove them as they are not needed.

b5a2cd070d Use SPDX header for license
Drop the lengthy license from each file and just use SPDX like most
projects nowadays. This doesn't have any change to license, just how
they are recorded in each file.

This follows the kernel approach: header files use '/*' for comments
while .c files use '//'. For .m4, use "#".

11eb9bc67c Use portable implementation for basename API
musl has removed the non-prototype declaration of basename from
string.h [1] which now results in build errors with clang-17+ compiler

Implement GNU basename behavior using strchr which is portable across libcs

Fixes
../git/tools/kmod.c:71:19: error: call to undeclared function 'basename'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
71 | "Commands:\n", basename(argv[0]));

3821e1971e add Zstandard compression support
I changed the style of the hackargs variable in autogen.sh to multiline
because said line was becoming a bit long with the new --with-zstd arg
added.

A previous version of this patch has been running on my two Arch Linux
installations (with an accompanying mkinitcpio patch) for several months
over many kernel updates without any issues.
Any additional testing and/or patch review would of course be appreciated.

ecab65b35c shared/util.c: assert_cc() can only be used inside functions
shared/macro.h has two versions of assert_cc, one that uses gcc
_Static_assert(), which requires recent enough gcc versions, and one
that uses a fake array to trigger a build error. The latter can only
work inside functions, so assert_cc() should only be used inside
functions.

Fixes the following build failure when building kmod with old gcc
versions such as gcc 4.3.x:

shared/util.c:52: error: expected identifier or '(' before 'do'
shared/util.c:52: error: expected identifier or '(' before 'while'

a6ede6c7ad util: fix warning of equal values on logical OR
shared/util.c: In function ‘read_str_safe’:
shared/util.c:211:24: warning: logical ‘or’ of equal expressions [-Wlogical-op]
    if (errno == EAGAIN || errno == EWOULDBLOCK ||
                        ^~
shared/util.c: In function ‘write_str_safe’:
shared/util.c:237:24: warning: logical ‘or’ of equal expressions [-Wlogical-op]
    if (errno == EAGAIN || errno == EWOULDBLOCK ||
                        ^~

This is because EAGAIN and EWOULDBLOCK have the same value. Prefer
EAGAIN, but add a static assert to catch if it's not the same in another
architecture.

88f6ffe449 util: remove dead code in freadline_wrapped
Each loop iteration starts with 'i < size'. When i is changed
the invariant is kept by checking if 'i == size' and growing the
buffer.

dea2dfee9b Remove FSF mailing address
It has changed in the past, and these days, anyone can get a copy of the
LGPL via the web rather than by post.

Like 657a122 (Remove FSF mailing address) in libabc by Josh Tripplet,
but let the FSF website in which the license can be found.

52c9c99056 Log error on failed underscores(), moving it to shared/
Move underscores() to shared/. It's the same as alias_normalize(), but
it rather operates in place, with the same string being passed.

The difference now that it's in shared/ is that it's a non-logging
function.

This makes us a little bit more verbose: we don't accept partially
correct module and aliases names in kcmdline and in configuration files.
We log an error instead.
