173aa78bcf pstree: fix theoretically unsafe code 
In practice, p->comm is never long enough to trigger the bug, but still.

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.

fea2588021 pstree: stop truncating thread names 
This also fixes a minor buffer overflow when displaying threads as
add_proc() only expects COMM_LEN bytes, but we give it one more than
that.

47f8558eee pgrep: fix -x option 
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.
