wsd: reduce tile logging from debug to trace level

These are very frequent and not very useful without
the ability to trace them across the system, which
are all done at trace level. So it's highly unlikely
that these would be used at debug.

leaflet: process the most common message first

The 'tile:' message is the most common and most
latency sensitive message, so give it priority.

wsd: tile serializer now supports adding a suffix

Moves appending tokens into the serializer and
avoids making extra copies of itself.

wsd: reuse ostringstream when logging

This is faster and reduces memory fragmentation.

Also, cleans up the logging macros and implementation.

wsd: use thread_local instead of __thread

The former is the standard C++ approach
and is reportedly faster than __thread
(at least with gcc).

wsd: use fast deflate level for png

The default deflate level of 6 is quite slow
and the benefits are hardly worth the high
latency that users experience.

Tested on a writer document with some small
images and a few pages of text:

Level 4 gives virtually identical compression
ratio to level 6, but is between 5-10% faster.

Level 3 runs almost twice as fast as level 6,
but the output is typically 2-3x larger.

Perhaps this should be exposed via config
so it would be possible to reduce latency
due to compression when CPU is scarce but
network bandwidth ample, and vice versa.
