Windows computers may produce a utf16 file from the command line that
contains a byte-order-mark. Along with handling the utf8
byte-order-mark, this also handles the utf16 for better Windows
compatibility.

Changes the `influx_inspect inmem2tsi` tool to stream each TSM/WAL
file and convert to a TSI index instead of loading the entire shard's
in-memory index first.
This adds a new flag -exact that will return exact counts instead of
estimates. The default is to return estimates since exact counting
on a problem shard could consume a lot of memory.
influx_inspect walks the data and wal directories building a list of
files to export. It then opens, reads, and exports each. If the file was
deleted between the time it was added to the list and the time the
inspect tool attempts to read it, the file is now skipped without
emitting an error.
There are several places in the code where comma-ok map retrieval was
being used poorly. Some were benign, like checking existence before
issuing an unconditional delete with no cleanup. Others were potentially
far more serious: assuming that if 'ok' was true, then the resulting
pointer retrieved from the map would be non-nil. `nil` is a perfectly
valid value to store in a map of pointers, and the comma-ok syntax is
meant for when membership is distinct from having a non-zero value.
There was only one or two cases that I saw that being used correctly for
maps of pointers.
This change provides a clear separation between the query engine
mechanics and the query language so that the language can be parsed and
dealt with separate from the query engine itself.
This switches all the interfaces that take string series key to
take a []byte. This eliminates many small allocations where we
convert between to two repeatedly. Eventually, this change should
propogate futher up the stack.
The Points channel is nil until after the subscriber service is opened.
If it is append before it's opened, the PointsWriter holds onto the
old reference.
