readproc still had some of the old API hanging around that
was good while we were trying it out, but its time to say
goodbye:
readproc.h removed from public procps.h header file
enum ns_type - not used - removed
get_ns_name() - not defined - removed
get_ns_id() - not defined - removed
PROCTAB proc_t only used internal to library
readproctab() and 2,3 friends not used - removed
proc_data_t was used by readproctab23() - removed
readtask() - not used - removed
read_cmdline() - copy,renamed and made generic - remove original
freeproc() - not used - removed
get_proc_status - not used - removed, however there should be
a new function created that does this. Given a PID return data
about it instead of scanning the entire procfs. Maybe it already does.
Left as internal-to-library only functions:
readproc(), readeither(), look_up_our_self(), openproc(), closeproc()
Updated libprocps.sym to export only what we use.
The includes used to define a lot of things a library include
should not. It was also a bit messy what was exposed in the library
and what was not.
get_pid_digits -> procps_pid_length and exported correctly
MALLOC attribute move into relevant .c files
NORETURN attribute moved to relevant .c, not used in library
PURE attribute removed, it wasn't used
KLONG/KLF/STRTOUKL were fixed for long, so now just use long
HIDDEN attribute removed. It was for 3 functions. The PROCPS_EXPORT
seems to do the same (opposite) thing.
likely/unlikely removed from most places, its highly debateable
this does anything useful as CPUs have gotten smarter about branches.
Re-arranged the includes, ALL external programs should just #include
<proc/procps.h> then proc/procps.h includes headers for files that
have exported functions. procps.h and the headers it includes should
not use items that are not exportable (e.g. hidden functions or
macros) they go in procps-private.h
Use the standard libc declarations.
For protecting the headers for C++ procps used to have its
own defines, this change makes them use the standard libc ones.
getstat() -> procps_stat_*
vminfo() -> procps_vmstat_*
These two components of the library now use the newer version of
the API with less exposed global variables. The old methods are
there for now.

procps automake defines restrict which means the binaries for procps
binaries compile. However external programs may not of defined
restrict which means they will not complie if they include files found
in /usr/include/proc.
Includes from libc6 use __restrict and if is good enough for
them, its good enough for us.
The devname.h requires readproc.h header which has dev_t. Unless
header is included the includes in program files must be in
correct order. I also added FIXME item to remind that for uid &
gid value int not correct data type but uid_t or gid_t from
pwd.h.
