man/man{2,3}const/*: Update POSIX history of constants

Hello all,

I'm continuing to update the first POSIX and SUS appearances of various system calls and functions, but I'm doubting that it's a good idea to wait and send all patches in at once. So while I continue, I'll try grouping related updates into patch sets and sending them through semi-regularly.

To start, this patch set consists of updates for documented constants in the 2const and 3const sections. I've provided a reference to the relevant POSIX version for each patch, providing links where possible.

In general, each patch concerns a separate page. However, if two pages share similar names and are referenced in the same section of POSIX (such that the citation given for both are the same), then I batched them together into the same patch.

Also perhaps noteworthy: if updating a page required only adding a POSIX or SUS version, I usually added it in a new line and left any other listed standards untouched. While if it required changing a line shared with other standards, I typically reformatted it to list each standard on a separate line (for nicer diffs with future changes).
