tzset(3) currently states that there are three TZ formats. The
first two it lists are actually variations of the POSIX-style
TZ format, of which there are at least five variations.
This patch corrects this to match the POSIX specification of
TZ having only two formats.

The TZ string representation indicates that the start/end
rules are required; this is incorrect.
Updated the TZ string format to the POSIX specification and
improve its readability by having only the optional parts in
italics.

Based upon reviewing the glibc source, the posixrules file is being used
for very specific TZ strings that can be represented as:
[:]stdoffsetdst[offset][,]
If anything follows the above string, even invalid data, posixrules will
not be used. Below is some shell output demonstrating this.
$ TZ="NZST-12:00:00NZDT-13:00:00,ANYTHING" \
strace -eopen date 2>&1 | grep -Ei 'posixrules|jan'

$ TZ="NZST-12:00:00NZDT-13:00:00," \

open("/usr/share/zoneinfo/posixrules", O_RDONLY|O_CLOEXEC) = 3

FILES section was overly verbose and included
environment variables. Added ENVIRONMENT section,
removing ENV VARS from the FILES section.
As stated in commit 2c7f200, /usr/share/zoneinfo/localtime
is not used, nor recommended by glibc.
