Add OPTION_NEGBIT and OPT_NEGBIT, mirroring OPTION_BIT and OPT_BIT.
OPT_NEGBIT can be used together with OPT_BIT to define two options
that cancel each other out.
Note: this patch removes the reminder from the test script because
it adds a test for --no-or4 and there already was one for --or4.

Add a way to recognize numerical options. The number is passed to
a callback function as a string.

Convert git-grep to parseopt.
The bitfields in struct grep_opt are converted to full ints,
increasing its size. This shouldn't be a problem as there is only a
single instance in memory.
