f8ebaa4985 Fix mktime's errno behavior. 
Don't touch errno on success, do set it to EOVERFLOW (the only allowed errno
value according to POSIX: http://pubs.opengroup.org/onlinepubs/9699919799/functions/mktime.html)
on failure.

We already had two copies of these constants, so time to factor them out
into bits/.

is my witness, there's a missing `const` here.

c508de0e41 Use sysinfo(2) to implement more of <sys/sysinfo.h>. 
We already had implementations of some of the functions, and I didn't
bother rewriting them when we added sysinfo(2). Ross Anderson said in
https://www.lightbluetouchpaper.org/2016/07/29/yet-another-android-side-channel/
that we should "simply disable access to all procfs files", which made
me curious how many places we use /proc in bionic. This is the one that's
obviously unnecessary. The others I'm not aware of alternative APIs for.
