test: nlist: make resilient against -Wl,--gc-sections
With linker sections GC enabled, we get a test failure in `nlist.c`:
```
nlist: nlist.c:72: main: Assertion `rc == 0' failed.
```
This turns out to be because several sections used by the test can be discarded:
```
ld: removing unused section '.text.func_pub' in file 'nlist.o'
ld: removing unused section '.bss.data_pub_uninit' in file 'nlist.o'
ld: removing unused section '.data.data_pub_init' in file 'nlist.o'
```
Reproduced with `CFLAGS="-Og -fdata-sections -ffunction-sections"` and
`LDFLAGS="-Wl,-O1 -Wl,--as-needed -Wl,--gc-sections -Wl,-z,start-stop-gc"`.
Additionally, `LDFLAGS="... -Wl,--print-gc-sections"` can help with diagnosing
which sections get removed.
We already mark these symbols as `used`, but we need `retain` [0] for them
to survive linker GC too.

build: Make almost all exposed interfaces use the new ABI selection
Explicitly select what to include as part of the target ABI, instead of
letting autoconfiguration potentially break ABI if the system grows
functionality provided by the library.
Make almost all the library selectable per target. Do not install manual
pages for interfaces not included in the library. Control inclusion of
symbols in map file via pre-processor macros, and move the comments
describing the ABI selection to configure.ac.
For now the header files are included as is and filtered through
pre-processor conditionals. Eventually they might get switched to be
autogenerated at build time.

test: Close all descriptors before initializing them for closefrom()
On macOS, closefrom() only sets the close-on-exec flag, so we cannot
check whether all file descriptors were closed, which means that if
on entry our file descriptor table was filled after the 4th file
descriptor, then we might fail the assertions for the flags for odd
file descriptors which we expect to be closed.
This can easily happen when running the test suite in parallel mode
with «make -j8 check» for example.

Define _NSIG if it is not defined by the system
At least on macOS this macro is not defined.

Declare environ if the system does not do so
The environ variable is supposed to be defined by the code using it, but
on glibc-based systems it will get defined if we request it, by including
<unistd.h> and defining _GNU_SOURCE.

Use lockf() when flock() is not available
On Solaris flock() is not available, and we should use instead lockf()
or fcntl().

test: Do not hardcode root:root user and group names
On some systems the root group is named wheel, and there is no root
group.

test: Fix closefrom() test on macOS
On macOS we do not close the file descriptors, and instead mark them all
as close-on-exec. So checking whether they are not valid does not work.

test: Fix closefrom() test to handle open file descriptor limits
If the system has configured a lower limit (either soft or hard) on the
number of open file descriptors, the test will fail. Make sure to check
whether we have exceeded that limit and adapt the max number of file
descriptors appropriately.

test: Disable blank_stack_side_effects() on non-Hurd systems
This code was added to cope with Hurd specific behavior, but it is
causing flakiness on containers on some Linux systems. Only enable
it where it is currently needed to try to get stability back on CI
systems.
Closes: #14

build: Do not enable ASAN for musl CI pipelines
musl-libc does not currently support ASAN, so enabling it makes
configure fail to detect libmd as it cannot link to it anymore.

man: Switch arc4random(3bsd) man page from OpenBSD to NetBSD
This gets rid of the last BSD-4-clause licensed file in the project.
The man page will probably need to be adapted to the current
implementation, but that can be done piecemeal afterwards.
Closes: #7

doc: Remove written-by attribution
While attribution is important, it is not relevant when tracking the
copyright holders for the work. And in any case it still stays in the
relevant source file.

test: Exempt blank_stack_side_effects() from sanitizer checks
This will mean we cannot use sanitizer support on the Hurd, for which
this function was added to fix the test. But the sanitizer suppression
function attribute is not having any effect, so this is better than
nothing.

man: Fix BSD and glibc versions
The versions used in the BSD macros are unknown, so they emit warnings,
extend or reduce them to use the two digit form. Correct the glibc
version when closefrom(3) got introduced.
