3c12b287ec touch: Avoid unnecessary call to stat 
Now, we first try a utimensat. If it succeeds, we are done, if not (and no -c
flag), create the file, then set the times with futimens.

2e5f1281ed touch: Use special UTIME_NOW and UTIME_OMIT values 
This allows users to touch files they have write access to, but aren't the
owner.

Also, remove utime.h include (not necessary since
4132561c17), and make sure to check the return
value of localtime (potentially preventing a NULL pointer derefence).

36a0a6cd92 touch: Remove useless variable 
The only possible return values of stat are 0 or -1, so it doesn't make sense to
store the return value in a variable to make sure it is not positive.

0941c9ab2c touch: Respect caller's umask 
Currently, if the caller has a umask of 002 or 000, the file gets created as 644
anyway.

Also, add O_WRONLY to the open call, since POSIX says that "Applications shall
specify exactly one of the first five values (file access modes) below in the
value of oflag".

8d96afd4fb touch: make invalid date an error and fix uninitialised value 
reproduce: touch -t 12345678 mytralala

would only give a warning and use uninitialised time values. The proper
way is to treat it as an error. Clear the "struct tm" and kill some lines
just in case.

95fb7364a8 Audit touch(1) 
Only minor things, as I already worked heavily on this tool a while
ago.
Fix style in the main loop and wording in the manpage.

d02327d0eb Get rid of the %Z-flag in strptime-format 
We don't actually need it for Zulu-time and handroll it.
We can add the gmt-offset to hour without range-checking, because
the implementation will take care of it in mktime().

ec8246bbc6 Un-boolify sbase 
It actually makes the binaries smaller, the code easier to read
(gems like "val == true", "val == false" are gone) and actually
predictable in the sense of that we actually know what we're
working with (one bitwise operator was quite adventurous and
should now be fixed).

This is also more consistent with the other suckless projects
around which don't use boolean types.
