088d77c3ae pmap: New switches - RC support (-n/-N,-c/C) & ShowPath (-p)
This commit introduces 4 new switches for the RC support
and 1 more switch for toggling the path printing
in the mapping field. the configuration file can be used
for a selection of columns to be displayed and for toggling
the path printing in the mapping field.

12ee64c8a3 pmap: fixing pidlist allocation & disabling vmflags in -X
This commit fixes allocation of the pid list so that it
is sufficient for storing the list terminator.

Additionally the vmflags printing in the -X mode is disabled
because it's too long. From now the vmflags are displayed
in the -XX mode only.

d454bfe902 pmap - removing the column width constraints in the -X/-XX modes
This commit changes the width measurement principle in the -X/-XX
modes so that a width of totals is measured instead of the width
of summands. The value of totals is always higher than the value
of summands. That additionally prevents the totals from having
a wrong indentation.

This commit also removes the minimum column width constraints
hardcoded to 7 characters.

20ce346ebd pmap: fixing broken indentation in the -X/-XX modes
This commit changes the processing principle of the -X/-XX modes
from 1-pass to 2-pass. A separate width measurement stage has been
added, so that the real maximum widths can be measured and used
for correct indentation.

The firstmapping variable now has a new value (2) used for the
width measurement stage (1st pass). The printing is disabled
in this stage. The file position is reset to the beginning
of the file once the end of file is reached and the printing stage
(2nd pass) begins.
It's questionable if this approach is sensitive to Read-after-Write
race conditions. Anyway, this feature is a good candidate for
a complete redesign in the future.

Additionally this commit introduces a final cleaning of the list
used for the evaluation of totals in the -X/-XX modes.

365a5fa517 pmap: empty output or crashes on ppc/s390 caused by wrong pidlist type
Previously the pidlist variable was defined as unsigned long *
whilst the openproc function accepts pid_t *.
Both target types differ in size (8 != 4) and therefore the issue
mainly affects big endian architectures.

This commit changes the pidlist type to pid_t * so that it's
compatible with openproc.

dca3c6d08f pmap vmflags support
Some new kernel version added a line in /proc/pid/smaps listing a processes vmflags. This broke pmap such that pmap -X and pmap -XX would always fail.

This patch adds support for the vmflags field so that -X and -XX work again AND they display the flags.

If KLONG != 8 the summary didn't print for RRS and Dirty, this commit
restores this behavour for both sizes.

7e8ee148d7 pmap avoid SEGV potential with new X/XX detail options
While permissions suggests that /proc/#/smaps contents
are world-readable, in practice this file might not be
available to a non-root process. Whether this is a bug
in the kernel or an intentional design decision really
makes no difference. This commit will protect pmap -X.

(everything is perfectly justified plus right margins)
(are completely filled, but of course it must be luck)

c043c47ddd pmap: use correct types for memory allocation
Fixes error which did not happen always.  Changes of being affected by

The debian bug referral can almost certainly reproduce the problem,
especially when tried multiple times in row.

(((char *) &((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct
malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size) >=
(unsigned long)((((__builtin_offsetof (struct malloc_chunk,
fd_nextsize))+((2 * (sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t))) -
1))) && ((old_top)->size & 0x1) && ((unsigned long)old_end & pagemask) ==
0)' failed.

fb11e1fe0a Changed the err and warns to macros
err and warn are BSD format but they are not recommended by library
developers.  However their consiseness is useful!

The solution is to use some macros that create xerr etc which then
just map to the error() function.  The next problem is error() uses
program_invocation_name so we set this to program_invovation_short_name

This is a global set but seems to be the convention (or at least errors
are on the short name only) used everywhere else.
