[PATCH] doc: clarify integer requirements in some functions

[Mike Frysinger]

These functions do not accept decimal values with fractional parts.
Describe them in terms of integers to clarify.

* doc/autoconf.texi: Change decimal to integer for m4_count, m4_max, m4_min,
and AS_VAR_ARITH.
* lib/m4sugar/m4sh.m4: Change decimal to integer for AS_FUNCTION_DESCRIBE,
AS_HELP_STRING, and AS_VAR_ARITH.
