9b56bf5416 lineedit: stop using permanent int_buf[] (16k!): allocate it
Now it is allocated temporarily only for the duretion of prefix generation,
and also we only allocate the needed size, not maximally possible.

81254ed387 lineedit: remove pos_buf[] array (up to 16k!); fix compat bugs
pos_buf is a strange hack, easy to do without it.
This also allows lines >32k long to be handled.
Also simplified match prefix generations and made behavior more like bash.

Decoupled variables reused for unrelated purposes: apparently,
when not forced to use liveness analysis, gcc fares better.

0834a6d3b9 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.
