Summary

This release of AWK includes a number of bug fixes and improvements,
including:

• Unicode support: AWK now supports Unicode input and output. This includes support for UTF-8 encoding, as well as the ability to process regular expressions and character classes over Unicode data.
• Improved CSV handling: AWK now provides better support for CSV data. This includes the ability to parse CSV files with embedded newlines, and the ability to generate CSV output with the --csv option.
• Fixed memory leaks: AWK has been fixed to eliminate a number of memory leaks. This includes leaks in the file management system, the regular expression engine, and various built-in functions.
• Improved error handling: AWK's error handling has been improved to provide more informative error messages and to prevent crashes in some cases.

(This is mostly a verbatim copy of upstream and I only uploaded it for completeness, thus self-approving).

Restore gensub() and some additional OpenBSD changes (except srandom and friends for now)

[bapt]

LGTM

[imp]

did you pull in the bsd-specific branch? Last time I imported, they were the same so we didn't need to 'preserve' anything in our tree.

This shouldn't have been necessary. ota upstream keeps a bsd branch that has the additions that we have in it.
If that's changed, I really want to look more closely at this import and separate out the additions from just the
upstream merge.

The proper branch to track upstream is 'bsd-features'. It gets merged with mainline each release, most recently Oct 30. I'll prep a review for that.

Warner is working on the import.
