Have /usr/bin/awk point to /usr/bin/nawk
100%
Description
Today, /usr/bin/awk points to a very old version of awk, also instantiated as "oawk":
omniosce(~)[0]% ls -lti /usr/bin/*awk
120141 -r-xr-xr-x 1 root bin 130908 Nov 13 00:12 /usr/bin/nawk*
120121 -r-xr-xr-x 2 root bin 94924 Nov 13 00:12 /usr/bin/awk*
120121 -r-xr-xr-x 2 root bin 94924 Nov 13 00:12 /usr/bin/oawk*
112828 -rwxr-xr-x 2 root bin 764576 Nov 13 00:12 /usr/bin/gawk*

In SmartOS, that has pointed to the more modern "nawk" for some time, AND oawk has been discontinued:
smartos(~)[0]% ls -lti /usr/bin/*awk
2737 -r-xr-xr-x 2 root bin 130996 Feb 28 10:44 /usr/bin/awk*
2737 -r-xr-xr-x 2 root bin 130996 Feb 28 10:44 /usr/bin/nawk*

Some software (e.g. https://dehydrated.io/) assume awk has nawk-level functionalilty. (That they may assume gawk-like features is another problem not addressed here.)
This issue proposes merely making "awk" hardlink to "nawk" instead of "oawk", keeping oawk and /usr/xpg4/bin/nawk around until distinct issues address their fates.

This seems pretty reasonable, assuming we've pulled in all the awk cleanup and test suite work Cody did in illumos-joyent. We'll want to make sure distributions that aren't already doing this on their own get a heads up for their release notes because there are certainly one or two very incorrect scripts that the old awk nonetheless used to allow which will now be correctly rejected.

It appears the awk cleanup done in illumos-joyent has made its way upstream as of #11552
nowhere(~/ws)[0]% diff -ru illumos-{gate,joyent}/usr/src/cmd/awk
nowhere(~/ws)[0]% diff -ru illumos-{gate,joyent}/usr/src/cmd/oawk
nowhere(~/ws)[0]%
Given the lack differences in oawk, it does appear that illumos-joyent uses `manifest` to effect the change specified in this bug. For upstreaming we'll have to modify Makefiles in both of the above directories (and system-extended-system-utilities.mf).
There ARE some usr/src/test subtle differences thanks to Joyent's OS-8022 (illumos-joyent:0a695497aef591f5c00620a61dffd4a0e4a5d47c), but they're only in three files and are small changes. They may go upstream as part of this fix.

Test differences between old and new are all about tmpfile names and awk now being nawk:

Also, the man page for awk now points to a modified version of the nawk page, and oawk is its own man page now.

Forgot to add awk test suite raw outputs. Doing so now.
