Add a zero-copy backend

Many facilities (logutil, stdout redirection etc) are to be
implemented in further commits, only writing is supported
so far.

It aims to minimize the cost of writing logs above all else.
When it comes to perf, it's pushin' it to the max, rollin' deep, baby.

Some traits:
 + limited syscalls (one per N logs)
 + no needless copies (writes directly to destination)
 - no way to monitor logs efficiently (which also has
   consequences for features like QoS)
 - kernel-based and somewhat convoluted

DLog-specific tweaks to FastLZ

 * add a way to calculate the minimum compression output buffer size
   as required by the interface. This should've probably been baseline.

 * remove the unsafety compiler parameter because I don't want anybody
   to actually tweak it. Removing this safety check is still possible,
   but now somebody has to get his hands dirty and be aware of what
   the exact consequences are, as opposed to just tweaking what is
   essentially an opaque knob.

 * add a comment detailing whence the code was taken.

Further commits are going to shuffle this chunk of code around
