1299a7651f Change mktime*(3) so that it does not always return EOVERFLOW when it cannot 
perform the conversion, but returns EINVAL when the time requested would fall
in the DST gap, or is not representable in the timezone requested, and document
this.

22bfd2bd63 Add code (not enabled) that allows mktime() to return a value for times 
in the DST gap when tm_isdst == -1, like glibc does. Document both behaviors.

221dcf2e47 Since localsub and gmtsub are called recursively to search for the local 
time, setting EOVERFLOW at the inmost level will unfortunately persist,
even if later calls to those functions succeed. Move the EOVERFLOW setting
to the top level calls.

48bf0eec29 Fix a bug reported by Gene, and debugged by Robert Elz. fsck_ffs can coredump 
if the timezone file fails to load, due to late initialization of sp->goahead
to false in tzload, causing localsub to return NULL in the "cannot happen"
case. The fix is belt and suspenders:
	- initialize sp->goback and sp->goahead very early in tzload
	- replace all malloc calls with callocs, and remove the bogus
	  casts (it is not the 70's anymore!)

- asctime{,_r}, ctime{,_r} may return NULL; document that, and avoid coredumps.
- gmtime{,_r}, localtime{,_r} may return NULL and set EOVERFLOW, document and
  set errno.
- when mktime returns (time_t)-1, make it set EOVERFLOW and document it.

fb535ac77e Make mktime(3) work with 64-bit time_t. 
The problem is that the tm_year field of "struct tm" is just an "int"
(per POSIX), and thus time_t values >  2^31*60*60*24*365 cannot
be converted. This made mktime(3) fail even if no such large time values
were passed in by user code because the algorithm does a binary search
over the time_t range which fails if a probe value cannot be converted.
To fix this, limit the time_t range to be scanned to 55 bits (which
is a bit on the safe side, but still good until y570855533).
This is more a stopgap fix, the overflow should be checked for
at other places as well (eg localtime(3)), and there are some more
limitations in timezone parsing code.

35a6eb4807 Make the declarations of wday_name and mon_name less eccentric. I 
suppose they were legal before, but lint was unhappy about them. It
was probably unhappy for the wrong reasons, but I think it certainly
wasn't something one would want anyway. Declaring a string of length
three to have storage of length three without room for the nul is
asking for trouble even if it does work in context, and there was no
reason not to state how many days there are in a week or months in a
year -- they aren't onerous and aren't going to change.

NOTE: If this code isn't being synced with the central TZCODE stuff,
it probably should be KNFed etc. It is full of K&R declarations,
register, lots of eccentricities, etc.
