2010-08-28pmap: new applet. +1k.Alexander Shishkin
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.
