libmount: when moving a mount point, all sub mount entries in utab should also be updated
Given that /run/mount/utab stores paths, this file needs to be adjusted when a
mount tree is moved.
However the moved tree may contains sub mount points in which case their utab
entries (if any) need to also be translated.
This patch takes care of that.
As suggested in https://github.com/systemd/systemd/issues/15266, a better
approach might be to store mount IDs instead of paths since mount IDs remain
unchanged when mount trees are moved.

meson: pass the correct absolute path to config.h
When building util-linux as a subproject inside another project (using
dependency fallback to get e.g. libuuid), `-include config.h` will not
work because it is generated private to util-linux. Build the project
argument using the path to the current build dir instead.
Meson has a global option -Ddefault_library which determines whether to
build all generic libraries as static, shared, or both. When creating a
library of the same name twice, once with library() and once with either
shared_library() or static_library(), some values for -Ddefault_library
will result in a fatal configuration error because multiple rules try to
create libXXX.a or libXXX.so
The reason for creating these additional copies of the library is in
order to optionally build some programs as both "prog" and "prog.static"
(and the latter is, of course, static). So depending on the
default_library value may not be desirable.

lsfd: (filter): parse "" in filter expression correctly
lsfd: (filter): fix a codeing style of if/else
lsfd: use /proc/$PID/map_files as the fallback information source
The original code scanning /proc/$PID/maps assumed two things; an entry
of the file contains a path started from '/' if a file is mapped, and
stat(2) works well with the path in the entry.
A mmap'ed socket breaks the former assumption.
tcpdump/lipcap does mmap an AF_PACKET socket to its address space!
A file is deleted after mapping breaks the latter assumption.
With this change, lsfd utilizes dentries under /proc/$PID/map_files
for gathering information of the mapped file in the case that the
assumptions are broken.
Private anonymous mappings are skipped to avoid wasting CPU time.
