Dropping some expensive dead code and avoiding some overloaded
method names to reduce confusion.

Eric Wong (5):
  over: rename ->connect method to ->dbh
  over: rename ->disconnect to ->dbh_close
  over: recent: remove expensive COUNT query
  over*: use v5.10.1, drop warnings
  msgmap: use v5.10.1

`->connect' is confused with the perlfunc for the `connect(2)'
syscall, and also `DBI->connect'.  Since SQLite doesn't use
sockets, the word "connect" needlessly confuses me.  Give
it a short name to match the field name we use for it, which
also matches the variable name used by the DBI(3pm) and
DBD::SQLite(3pm) manpages.

Since we got rid of over->connect, `disconnect' no longer pairs
with it.  So name it after the `close(2)' syscall it ultimately
issues.

As noted in commit 87dca6d8d5988c5eb54019cca342450b0b7dd6b7
("www: rework query responses to avoid COUNT in SQLite"),
COUNT on many rows is expensive on big SQLite DBs.

We've already stopped using that code path long ago in WWW
while -imapd and -nntpd never used it.  So we'll adjust our
remaining test cases to not need it, either.

v5.10.1 lets us use the lighter parent.pm instead of base.pm,
and we'll rely on the shebang to enable warnings (or not).

While we're in the area, drop a no-longer-necessary import for
PublicInbox::Search, since OverIdx doesn't require search.

We use the defined-or (`//', `//=') operators in 5.10,
so require 5.10.1 like the rest of our codebase.  Update
an outdated comment while we're at it.
