c70b9fe882 awk: Use random(3) instead of rand(3)
While none of them is considered even near to cryptographic
level, random(3) is a better random generator than rand(3).

Use random(3) for awk as is done in other systems.

Thanks to Chenguang Li for discussing this in the lists
and submitting the patch upstream.

8a2222286c backport ERE interval/repetition expressions from Apple awk-24
The lack of POSIX interval expressions[*] (a.k.a. bounds, a.k.a.
repetition expressions) in regular expressions is listed under BUGS
in 'awk.1'. Apple's version of onetrueawk has supported these since
at least 2009, judging by the date stamp on their src/b.c in:
https://opensource.apple.com/tarballs/awk/awk-24.tar.gz

A bug report prompted NetBSD to swiftly integrate this code into
their awk. This commit is based on that NetBSD diff.

f3e4c4ca1d

b.c:
- Backport POSIX-standard interval expressions support in regular
  expressions via NetBSD from Apple awk-24 (20070501).

main.c:
- Bump version ID.

FIXES:
- Add note and credit for this feature.

awk.1: section BUGS:
- Remove line saying interval expressions are not supported.
