Import grepc(1) (script and manual page) from separate project
It started as a script in the Linux man-pages project, under scripts/
within scripts/bash_aliases.
Eventually, I turned it into a large script, and moved it into a
separate project, to be able to work on it more freely.
The original scripts were removed from this project in commit
c3752af0549c (2022-11-22; "bash_aliases: Remove grep_syscall(),
grep_syscall_def(), and grep_glibc_prototype()").
Now, grepc(1) has stabilized, and I find it very useful for maintaining
this project (as well as others), so let's merge it back. This will
allow distros to package it sooner than if it remained as a standalone
project.
I've imported the git history (ignoring files we don't care about) with
the help of git-filter-repo(1).

Call pcre2grep(1) only once, which allows removing named pipes. This is

It has a caveat: this single call to pcre2grep(1) will consume more
resources, and will crash on certain input files. The workaround is to
restrict the search to just one or a few types of code. Document this
in the manual page. This caveat only applies to very specific files,
which so far I've only found in the Linux kernel source tree.

consider adding back a recursive mode if necessary.
Also, don't remove the two blanks at the start of the output, for

grepc, grepc.1: Remove -tu from the defaults
Normally, one either wants to see a declaration/definition, or its
uses, but not both at the same time. Also, there are usually many
more use sites than than definitions, and therefore definitions
are shadowed between all the noise. Restrict the default to
declarations and definitions, which in my experience seems to be
the most common use case.

grepc: Fix grepc_type_typedef_underlying_struct_union_enum
When it calls grepc_type_struct_union_enum(), it needs to use a
different file list, since it's searching for an identifier
different from the one passed in the command line.
Also, while at it, improve the quoting of the pattern passed to
pcregrep(1).
