* rename flags functions to scols_table_enable_*
* rename *_no_foo() functions to _nofoo()
* output formats are mutually exclusive, so don't use flags there
* don't assume symbols in scols_new_table(), use scols_table_set_symbols()

prlimit.c: Alternatively to applying the limits to an existing process via the
--pid option, allow a command to be executed. Adapted usage() accordingly.
prlimit.1: mention new syntax.

This patch makes the code more robust. We should not share the same
pointer for old and new arguments for prlimit(2) syscall.

# prlimit --nofile=:4000 --pid $$
When the PID is given later than a partially given limit, then prlimit
used the current PID for getting the missing part (hard, soft) of the
limit.
Factored out the retrieval of the unknown limit from parse_prlim() to
new get_unknown_hardsoft() which is to be called by do_prlimit() based
on the struct prlimit member 'modify' set by add_prlim().
[kzak@redhat.com: - use prlimit->mofify as mask
- add soft vs. hard limit check from another
Bernhard's patch]

- differentiate between set and get operations
- add limit name to the error message
- remove PID from the message (whole util works always with only one
PID, so this info is superfluous)

Fix option parsing: prlimit ran into usage() if called
without arguments which should only be done for surplus
arguments. Instead, it should display all limits.

This program uses the prlimit() system call to get and/or set resource limits
for a given process.
[kzak@redhat,com: - improve <soft:hard> parsing,
- use short cmdline options compatible with ulimits
- add --verbose mode
- fix gcc warnings]
