Return from check_file() and check_file2() functions when maximum name
depth is reached. The use unsafe strncpy() is also removed just to be on
safe side.

This change fixes all shadow declarations. The worth while to mention
fix is with libfdisk sun geometry. It comes from bitops.h cpu_to_be16
macro that further expands from include/bits/byteswap.h that has the
shadowing.
libfdisk/src/sun.c:961:173: warning: declaration of '__v' shadows a previous local [-Wshadow]
libfdisk/src/sun.c:961:69: warning: shadowed declaration is here [-Wshadow]
libfdisk/src/sun.c:961:178: warning: declaration of '__x' shadows a previous local [-Wshadow]
libfdisk/src/sun.c:961:74: warning: shadowed declaration is here [-Wshadow]
That could have caused earlier some unexpected results.

It's better than monitor utab directly. The utab is updated by
rename(2) and it's really tricky for inotify, because it's necessary
to monitor all /run/mount directory and then it's necessary to verify
that the renamed file is really "utab".
The new concept is without possible false positives and it also
triggers the change when utab update is really done.

We need full control on changes evaluation, so it's better to
hide all in our private epoll. This change also significantly
simplify the API.
mn = mnt_new_monitor();
mnt_monitor_enable_userapce(mn, TRUE, NULL);
mnt_monitor_enable_kenrel(mn, TRUE);
fd = mnt_monitor_get_fd(mn);
...
<use 'fd' in epoll controlled by your application>
...
while (mnt_monitor_next_changed(mn, &filename, NULL) == 0)
printf("%s: change detected\n", filename);

The patch introduces mnt_monitor_enable_*() functions (now for
userspace only) to make the API easy to use for high-level purpose.

Also use the standard macros, and correct the synopsis: use angular
brackets and show that look accepts multiple files.

Use two separate strings for the two different forms of setarch,
instead of filling in an untranslated word into a single string.
Also use the standard angular brackets for nonliteral arguments.

Commit c372860ddb accidentally removed
the alternative form of setarch in which the command name specifies
the architecture to be set. Also improve some formatting.

Also, the resource option -a is not valid with -i, so show the valid
ones explicitly. Also gettextize the synopsis as a single string, as
the two lines are tightly related and other synopses do this too.

This adds a concise description of a tool to its usage text.
A first form of this patch was proposed by Steven Honeyman
(see http://www.spinics.net/lists/util-linux-ng/msg09994.html).

The 'if' clauses that have termination as either of the control flow
results will never need 'else'. Making the termination to happen true
flow is enough.

Shell null check is redundant. The shell can be null only after
ask_new_shell returned such, and that is checked earlier in program
logic.
Secondly the check_shell does not need to return values, in such cases
the program can simply exit.

Rename prompt() to ask_new_shell(). Remove fixed size buffer and
allocate path to new shell, that should make Hurd people happy. Use
strutils.h for white space trimming.

Earlier setting a /bin/sh was impossible for users that had nothing set
as shell, as that was seen as no change.

Use of fgets() can make a single long line to be understood as two
entries, and someone could play tricks with the remainder part of the
buffer.

The function shmctl() has to be called with 'struct shmid_ds', and if
you need 'struct shminfo' then the right way is to cast:
bad way:
struct shm_info info;
shmctl(0, SHM_INFO, &info);
right way:
struct shmid_ds buf;
struct shm_info *info;
shmctl(0, SHM_INFO, &buf);
info = (struct shm_info *) &buf);
The patch also fixes bug in ipc_shm_get_limits() where is missing
lim->shmmax in code based on shmctl().
