Portability fix: use unsigned cast to guaranteed positive part of expression
in case {L}LONG_MAX > abs({L}LONG_MIN). Non-functional change - we don't
have any such platforms.

Remove rcsids and unneded include

'acc' is not initialized in one hypotetical case, fix it

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 sam

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.

Impliment the ISO-C99 strto[u]ll()
and rewrite strto[u]q() in terms of it.

Get rid of integer overflow warning.

Similar changes like in strtol, all this family is VERY broken
in 8bit environment (isalpha at the end of digits)
