Fix case-insensitive match in ACL checking

ACL checking of DokuWiki is currently always case-sensitive
regardless of auth backend setting ($auth->isCaseSensitive).
This commit enables case-insensitive match in the same way
of auth_isMember().

Ignore empty email headers

Typo fix for TL;DR

New Tar Archive library

We now have two defines for checking for UTF-8 and Unicode property
support in PREG and use them to work around FS#2636 on older systems.

fixes the problem with missing innerText in Firefox (and other browsers)
and corrects shortening in regard to paddings and the use of the
text-overflow attribute

we now touch the messages before the actual update happens. this should
lower the chance of more than one update check running at a time.

In the recent refactoring of the HTTPClient, a problem with certain
systems was reintroduced. On these systems a select() call always
waits for a timeout on the first call before working properly on the
second call.

This patch reintroduces the shorter timeouts with usleep rate limiting
again.

Since this bug is not reproducible on other systems it can't be unit
tested unfortunately.

Added PAGEUTILS_ID_HIDEPAGE Event

fix E_STRICT errors FS#2427

add index file similar to fileicons to show active smileys

The library now creates either a POSIX ustar prefix or a GNU longlink
entry for files which have a name longer than 100 bytes

Supports POSIX ustar prefixes and GNU longlink entries
