Add new psql help topics, accessible to both --help and \?.
Add --help=<topic> for the commandline, and \? <topic> as a backslash
command, to show more help than the invocations without parameters
do. "commands", "variables" and "options" currently exist as help
topics describing, respectively, backslash commands, psql variables,
and commandline switches. Without parameters the help commands show
their previous topic.
Some further wordsmithing or extending of the added help content might
be needed; but there seems little benefit delaying the overall feature
further.

psql: fix \connect with URIs and conninfo strings
This is the second try at this, after fcef1617295 failed miserably and
had to be reverted: as it turns out, libpq cannot depend on libpgcommon
after all. Instead of shuffling code in the master branch, make that one
just like 9.4 and accept the duplication. (This was all my own mistake,
not the patch submitter's).
psql was already accepting conninfo strings as the first parameter in
\connect, but the way it worked wasn't sane; some of the other
parameters would get the previous connection's values, causing it to
connect to a completely unexpected server or, more likely, not finding
any server at all because of completely wrong combinations of
parameters.
Fix by explicitely checking for a conninfo-looking parameter in the
dbname position; if one is found, use its complete specification rather
than mix with the other arguments. Also, change tab-completion to not
try to complete conninfo/URI-looking "dbnames" and document that
conninfos are accepted as first argument.
There was a weak consensus to backpatch this, because while the behavior
of using the dbname as a conninfo is nowhere documented for \connect, it
is reasonable to expect that it works because it does work in many other
contexts. Therefore this is backpatched all the way back to 9.0.

(probably earning a Gierth's "Sloppy" badge in the process.)

Add new psql help topics, accessible to both --help and \?.
Add --help=<topic> for the commandline, and \? <topic> as a backslash
command, to show more help than the invocations without parameters
do. "commands", "variables" and "options" currently exist as help
topics describing, respectively, backslash commands, psql variables,
and commandline switches. Without parameters the help commands show
their previous topic.
Some further wordsmithing or extending of the added help content might
be needed; but there seems little benefit delaying the overall feature
further.
