This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.
Revert with prejudice.
This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.
Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

These changes are incomplete but are making it difficult

Don't check for __SERR which may stick from one of any previous stdio
functions.
__SERR is for user and the rest of stdio code do not check it
for error sensing internally, only set it.
In vf(w)printf.c here it is more easy to save __SERR, clear and restore it.

NetBSD, OpenBSD, and Android's Bionic all number the clauses 1 through 3,
so follow suit to make comparison easier.

If the size passed to {,v}s{w,n}printf is larger than INT_MAX+12012-04-21T06:10:18ZDavid Schultzdas@FreeBSD.org2012-04-21T06:10:18Zurn:sha1:666d00d34aa1b075412f216f191def6b6f3e2c88
(i.e., the return value would overflow), set errno to EOVERFLOW
and return an error. This improves the chances that buggy
applications -- for instance, ones that pass in a negative integer
as the size due to a bogus calculation -- will fail in safe ways.
Returning an error in these situations is specified by POSIX, but
POSIX appears to have an off-by-one error that isn't duplicated in
this change.
Previously, some of these functions would silently cap the size at
INT_MAX+1, and others would exit with an error after writing more
than INT_MAX characters.

the global locale, making them take an explicit locale parameter. Also
adds support for per-thread locales. This work was funded by the FreeBSD
Foundation.
Please test any code you have that uses the C standard locale functions!

chance of returning an error if stack garbage happens to be equal to
(size_t)-1 or (size_t)-2.
