Update pear-Log package from 0.8.4 to 1.12.0, fixing PR pkg/42673.

Changes are too huge to show here, please refer:
http://pear.php.net/package/Log/download/All.

And now, this pacakge supports PHP5 only.

1.12.0

This release drops PHP4 compatibility (enforced by the package dependencies).

There is unfortunately no way to support both PHP4 and PHP5 in the same code
base when running under E_ALL. Because it appears that the majority of Log
package users have moved to PHP5, the Log package now targets that audience.

Given the fact that the Log package is now largely in maintenance mode,
existing PHP4 users shouldn't feel adandoned. If necessary, important fixes,
etc. can be merged back into the 1.11.* release line, which will retain PHP4
compatibility.
