86a7f18f21 *: Switch to POSIX utmpx API 
UTMP is SVID legacy, UTMPX is mandated by POSIX.

Glibc and uClibc have identical layout of UTMP and UTMPX, both of these
libc treat _PATH_UTMPX as _PATH_UTMP so from a user-perspective nothing
changes except the names of the API entrypoints.

7df1f1dda1 top: fix and merge code to parse /proc/meminfo 
display_header() code to parse meminfo as is was buggy:
- uninitialized variables were used if meminfo was not as expected
- meminfo parsing failed on new kernels (3.14+) as new field 'MemAvailable'
  was introduced between MemFree and Buffers
- shared memory was handled only for ancient kernels (2.4.x and earlier)

as result Buffers and shared memory fields were shown with bogus values
on current kernels.

The new code does not try to parse the old style summary header, as the
separated fields are always present (it saves code size). Additionally,
both Shmem (2.6+) and MemShared (2.4 and earlier) fields are now parsed
and summed for shared memory usage; as only one of them exists depending
on kernel version.

display_topmem_header() parses also meminfo so this makes it use the
same code for code shrink.

879f008a8f lsof: correct check for symbolic link 
Busybox lsof used the d_type field of a 'struct dirent' to verify whether the
entry is a symbolic link. This field, however, is not portable. On at least
one board [1] I have seen, that field is 0, and the check fails even though
the entry is a link.

The explicit check for a symbolic link is really only needed to skip the
default directory entries '.' and '..'. The directory /proc/<pid>/fd/
should not contain anything else but these two and symbolic links.
With these assumptions, this patch replaces the explicit link check with a
basic check for '.' and '..' (and any hidden file). In the unlikely case that
there are other file types, xmalloc_readlink() will return NULL, and we can
skip the entry.

[1] A MIPS-based board with glibc 2.9, Linux 2.6.32.27.

Because when -x is used (exact match), then we cannot compile the
regular expression with REG_NOSUB. The manual page regcomp(3) states
in section "Byte offsets":

    Unless REG_NOSUB was set for the compilation of the pattern
    buffer, it is possible to obtain substring match addressing
    information.

The problem was detected on an ARM system with glibc 2.16.
