.mlrrc files may now contain INI-style named sections ("profiles"):
# Global settings, applied always:
icsv
[j]
ojson
jvstack
[tsvout]
otsv
Lines before any section header are global settings, applied always, so
existing .mlrrc files behave exactly as before. The new main flag
--profile {name} (alias -P {name}) applies the settings from the [name]
section after the global settings; without it, sections are ignored
entirely (their lines aren't even parsed).
It's a fatal error if a requested profile has no matching section in any
.mlrrc file processed, if no .mlrrc file was found at all, or if
--profile is combined with --norc or MLRRC=__none__.
Also fixes the regression-tester to restore per-case environment
variables to their prior values after each case, rather than setting
them to the empty string -- needed so cases pointing MLRRC at a test
file don't clobber the suite-wide MLRRC=__none__ guard.
Includes unit tests, regression-test cases, and doc/man-page updates.

Datatypes for parsing the Miller command line, and the flags table.
pkg/climainis the flag-parsing logic for supporting Miller's command-line interface. When you type something likemlr --icsv --ojson put '$sum = $a + $b' then filter '$sum > 1000' myfile.csv, it's the CLI parser which makes it possible for Miller to construct a CSV record-reader, a transformer chain ofputthenfilter, and a JSON record-writer.pkg/clicontains datatypes and the flags table for the CLI-parser, which was split out to avoid a Go package-import cycle.
