Add cross-references to wide character versions of these functions.

Style: One space between "restrict" qualifier and "*".

mentioned above plus strtouq and strtoq.
- Update the prototypes in the manual pages.

mdoc(7) police: fix markup, bump document date.

Implement strtoimax() and strtoumax()

mdoc(7) police: changed pure POSIX text; added missing markup bits.

Move to using .In instead of .Fd #include <> for include mark-up.

Inspired by comment from: dd

Locale *is* used in strto*l*(), at least for isspace(), so remove
'locale not used' statement from comments and BUGS section of manpage.

strtol(): fix non-portable 'cutoff' calculation using the same method as
in strtoll().

Cleanup 'cutoff' calculation, remove unneded casts. Misc. cleanup to
make all functions looks the same.

Implement EINVAL reaction per POSIX, document it in manpage, corresponding
POSIX example quotes here:

------------------------------------------------
If the subject sequence is empty or does not have the expected form, no
conversion is performed; the value of str is stored in the object pointed
to by endptr, provided that endptr is not a null pointer.

If no conversion could be performed, 0 shall be returned and errno may be
set to [EINVAL].

[EINVAL] The value of base is not supported.

Since 0, {LONG_MIN} or {LLONG_MIN}, and {LONG_MAX} or {LLONG_MAX} are
returned on error and are also valid returns on success, an application
wishing to check for error situations should set errno to 0, then call
strtol( ) or strtoll ( ), then check errno.
