There are subtle inconsistencies, like "01" being a valid decimal but not
a valid integer, which vaguely bug me. Cleaning this up, and the corresponding
parser logic.
A number can't have leading spaces because the grammar doesn't
put spaces in them in the first place, so stop accepting them in the
number syntax. This should never have any impact on anything,
it's just simpler.
Update a couple of test cases to reflect this -- no longer testing
that trailing spaces are okay, now testing that they're not, for
instance.
- all tests green on RoaringTx
- RoaringTx on by default
- blueGreenTx testing framework available for A-vs-B comparison
of Tx implementations
- flag -tx added to server command line but not wired to
change NewIndex() selection yet.
- 918 green tests, 14 tests red on BadgerTx.
A full list of the 14 red tests on BadgerTx follows.
Note that these red tests represent not defects in BadgerDB
or BadgerTx but rather failures of the pre-existing pilosa infrastructure to yet
be fully adapted from files to using a transactional storage engine.
As such these are tests that RBF should not be expected to
pass yet either.
Fixing the pilosa infrastructure to allow these tests
to go green under Badger is the next and highest priority
order of business, but RBF can get much testing benefit
from the 918 green tests we do have, and hence we merge
as much as we have today.
The 14 red tests when NewIndex() is set to use
BadgerTx are as follows. Note in particular
that pilosa cluster resizing is not working yet under a
transactional store.

It turns out that it's not very useful to keep the sign
value as a separate argument in the pql.Decimal struct.
This commit incorporates it into Value, and makes Value
an `int64` (for some bone-headed reason I had made it a
`uint32` before which is just dumb).
This commit introduces a new type: pql.Decimal
We use that instead of float64 in order to ensure
that the string representation is consistent.
One unfortunate discovery during implementation is
that the RowAttrs and ColAttrs support floats, and
the PEG file was treating them as such. So I had
to split the PEG definitions into float-specific
items and decimal-specific items.
