Truncate the time interval output of the monitor service to be on even
time intervals rather than on every minute based on the start time. This
normalizes the output from the monitor service.
The tsdb package had a substantial amount of dead code related to the
old query engine still in there. It is no longer used, so it was removed
since it was left unmaintained. There is likely still more code that is
the same, but wasn't found as part of this code cleanup.
influxql has dead code show up because of the code generation so it is
not included in this pruning.
The highest time represented by a nanosecond needs to be used for an
exclusive range, so the maximum time needs to be one less than the
possible maximum number of nanoseconds representable by an int64 so that
we don't lose a point at that one time.
Previously worked in the open source version because the timestamp used
for finding a shard would be truncated by the retention policy so the
lookup time didn't run into this edge case because it didn't rest on the
truncation boundary. Since that point didn't really belong in that shard
group and was placed there by mistake, it's best to fix this bug since
the timestamp used to create the shard group should be capable of
retrieving it.
The code for parsing a key our of the WAL or TSM files in the engine
was naive and didn't account for measurements with escape chars. This
uses the correct parsing code to parse and load them correctly.
Fixes#6496
Influx does not support fields with empty names or points
with no fields.
NewPoint is changed to validate that all field names are non-empty.
AddField is removed because we now require that all fields are
specified on construction.
NewPointFromByte is changed to return an error if a unmarshaled
binary point does not have any fields.
newFieldsFromBinary is changed to prevent an infinite loop that
can arise while attempting to parse corrupt binary point data.
TestNewPointsWithBytesWithCorruptData is changed to reflect the
change in the behaviour of NewPointFromByte.

These tests check that NewPoint and NewPointFromBytes return an error if:
* arguments specify a point with no fields
* arguments specify a point with a field that has an empty name
These tests also check that Point.Fields() always returns, even in the presence
of corrupt binary data read with NewPointFromBytes.
These tests fail at this commit and are fixed by a subsequent commit.

byte.Replace will return a copy of the input even when nothing has
been replaced. This is called in lower level query execution and
create some garbage that isn't necessary.
Quotes are handled differently in the line protocol depending on when
they are encountered. Quotes in field values matter, quotes anywhere
else don't.
`scanLine()` didn't understand this difference and treated all quotes
the same as ones for tag values. This resulted in `scanLine()` reading
the wrong amount of data sometimes when quotes were involved.
This fixes#5204.
Quotes are not supposed to be significant in field keys, but are
significant in field values. The code as it currently was would
consider quotes in a key to be significant, but the later parser that
would unmarshal the fields from the byte string did not consider those
quotes to be significant. This meant that the following string:
"a=1
The line protocol parser would see a mismatched quote instead of a valid
input to the line protocol. But more nefariously, the following string:
"a=1"=2
The line protocol parser would ignore the first equals since it is
located in the quotation marks and think this was a valid input. It
would then pass it on to the field parser who would panic and die when
it tried to parse `1"=2` as a number.
Fixes#4076.
Mainly for debugging as since this should not happen going forward. Since
there may be points with NaN already stored in the WAL, this is helpful for
troubleshooting panics.
Float values are not supported in the existing engine and the tsm1
engines. This changes NewPoint to return an error if a field value
contains a NaN field. It also allows us to validate fields to prevent
other unsupported types from sneaking in through other input plugins.
