riastradh | strptime(3): Declare digit d as time_t.
This doesn't make a semantic difference -- d can only take on the ten
values {0,1,2,3,4,5,6,7,8,9}, and the arithmetic with it later all
comes out the same whether the type is unsigned or time_t, even if
time_t were int32_t instead of int64_t.
But it pacifies overzealous compilers used by downstream users of
this code. And while it's silly to use a much wider type (64-bit
signed) than is needed here to store a single digit, it doesn't
really hurt either (32-bit unsigned is much larger than needed too).

Correct range for ISO week conversion
The %V conversion range for strptime(3) should match the strftime(3)
conversion range. A valid ISO week is 1-53.

The military/nautical time zones were added following RFC 822 and RFC
2822 specifications. Unfortunately they are specified incorrectly in
RFC-822 and not very clearly in RFC 2822. RFC 1123 clearly states they
are specified incorrectly - counting the wrong way from UTC - in RFC
822. RFC 2822 just states they were implemented in a non-standard way.
Mea culpa for not noticing when originally implemented. Fix them so
the correct calculations are made.

Changes affecting code
localtime no longer mishandles America/Anchorage after 2037.
(Thanks to Bradley White for reporting the bug.)
The localtime module allows the variables 'timezone', 'daylight',
and 'altzone' to be in common storage shared with other modules,
and declares them in case the system <time.h> does not.
(Problems reported by Kees Dekker.)
On platforms with tm_zone, strftime.c now assumes it is not NULL.
This simplifies the code and is consistent with zdump.c.
(Problem reported by Christos Zoulas.)
Changes affecting documentation
The tzfile man page now documents that transition times denote the
starts (not the ends) of the corresponding time periods.
(Ambiguity reported by Bill Seymour.)

itohy | Passing "char" values to ctype(3) functions is problematic.
If an argument of a ctype function is outside "unsigned char"
and if it is not EOF, the behavior is undefined.
The isascii(3) is the sole exception of above and it was used to
be used to check a value was valid for other ctype functions in
ancient systems. On modern systems, the ctype functions take
all values of "unsigned char", and this check is obsolete and
even wrong for non-ASCII systems. However, we leave the isascii()
untouched for now, so as not to change the current behavior.

If port provides __weak_alias(), provide an Standard C and POSIX pure
identifier namespace by renaming non standard functions and variables
such that they have a leading underscore. The library will use those
names internally. Weak aliases are used to provide the original names
to the API.
This is only the first part of this change. It is most of the functions
which are implemented in C for all NetBSD ports. Subsequent changes are
to add the same support to the remaining C files, to assembly files, and
to the automagically generated assembly source used for system calls.
When all of the above is done, ports with weak alias support should add
a definition for __weak_alias to <sys/cdefs.h>.
