Reverted LD_LIBRARY_PATH changes to fix netatalk build
netatalk: Since the build system trashes Asus's customized configure (and trying to do it properly creates more issues), let's copy a backup of it before configuring - for now
Merge branch 'master' of github.com:RMerl/asuswrt-merlin
netatalk: Remove cnid cdb support, to be in-sync with Asus (and also because it's unneeded)
netatalk: Re-add corrected location for libgcrypt-config
Bumped revision to 374.42_2
libshared: ensure the backup vars are the same size as what gets copied to it - keep them signed however as it can potentially contain a negative value
Updated documentation
Reapply "netatalk: Disable checking for dtrace"

If dtrace was detected on the host it would be enabled, even
though it's not available on the target.

Reapply commit 5497d31 which was unintentionally reverted in 1d3f779.
netatalk: fix modified configure
webui: Don't process DLNA paths if DLNA isn't enabled, so we can support enabling only DAAPD
Merge branch 'master' of github.com:RMerl/asuswrt-merlin
Bumped revision to 374.43 alpha 1
Merge pull request #625 from saintdev/for-upstream

Fix Asus modified netatalk configure v2
webui: Display a warning on the Performance tab if current bootloader doesn't support Turbo mode (AC68U)
lan: Fix broken BROUTING rule that no longer prevented router access from restricted guests (was broken in GPL 4887)
Provide an empty WPAD URL for broken Windows/IE clients.

I considered making it default to http://router.asus.com/ which would have provided
out-of-the-box support for PAC (Asuswrt-Merlin supports it), but I feared that it
might have caused long delays for clients using the router DHCP but not its resolver.

This change in behaviour means that people using a customized WPAD option will need
to use a postconf script to modify the existing entry now instead of just appending
it to the existing options.
