ad00e7ff82 database: Stop writing block header data to LevelDB.
Now that all headers are stored in the in-memory index, the database
bucket managed by blockchain, and in the flat files, it makes sense to
drop the redundant data from the block index bucket in ffldb.

To avoid modifying the database interface, this reimplements
FetchBlockHeader(s) to use header data stored in flat files. This can
be trivially implemented by delegating to FetchBlockRegion.

a6965d493f all: Remove seelog logger.
The btclog package has been changed to defining its own logging
interface (rather than seelog's) and provides a default implementation
for callers to use.

There are two primary advantages to the new logger implementation.

First, all log messages are created before the call returns.  Compared
to seelog, this prevents data races when mutable variables are logged.

Second, the new logger does not implement any kind of artifical rate
limiting (what seelog refers to as "adaptive logging").  Log messages
are outputted as soon as possible and the application will appear to
perform much better when watching standard output.

Because log rotation is not a feature of the btclog logging
implementation, it is handled by the main package by importing a file
rotation package that provides an io.Reader interface for creating
output to a rotating file output.  The rotator has been configured
with the same defaults that btcd previously used in the seelog config
(10MB file limits with maximum of 3 rolls) but now compresses newly
created roll files.  Due to the high compressibility of log text, the
compressed files typically reduce to around 15-30% of the original
10MB file.

multi: Update markdown files for GFM changes.
The github markdown interpreter has been changed such that it no longer

updates all of the markdown files accordingly.

While here, it also corrects a couple of inconsistencies in some of the
README.md files.
