libbb: add a function to make a copy of a region of memory
...
Introduce a library routine to package the idiom:
p = xmalloc(b, n);
memcpy(p, b, n);
and use it where possible. The example in traceroute used xzalloc
but it didn't need to.

pmap: new applet. +1k.
...
pmap is a tool used to look at processes' memory maps, normally found
in procps package. It provides more readable and easily sortable output
(one line per mapping) from maps/smaps files in /proc/PID/. This would
help in debugging memory usage issues, especially on devices where lots
of typing is not a viable option.
This patch does'n implement -d and -A command line options of GNU pmap,
since those are not that must have features and I was afraid of going
blind from looking at its code.
The implementation takes smaps scanning part out of procps_scan() function
and moves it into procps_read_smaps(), which does more detailed processing
of a single PID's smaps data.
