Fix wait time computation with auth_user
When using auth_user, the transition to the CL_WAITING_LOGIN state
would not initialize the client->wait_start field. This would either
lead to garbage values being recorded, or under assertions enabled it
would crash in activate_client().
(test_auth_user was actually reproducing this problem, but a crash
requires assertions enabled and new memory being all zero, so it was
difficult to catch it.)

Rewrite man page filter to work independent of Pandoc
This allows it to work with really old Pandoc versions that don't have

Fix idle_transaction_timeout calculation
idle_transaction_timeout should count from the last request of the
server, because the server sent the idle information. The code
previously used the last request of the client, which could lead to
premature timeouts.
It seems that many contributors already submit patches thinking that
rst is Markdown, which leads to incorrect and inconsistent formatting,
since the two are similar but not compatible. By using the more well
known Markdown, we can perhaps hope to achieve better formatted
documentation contributions.
Also, since the web site uses Markdown as its source format, by using
Markdown here we can avoid the fragile conversion process altogether.
Once upon a time, one could point auth_file to pg_auth in the
PostgreSQL data directory, but this is long obsolete (gone as of
PostgreSQL 9.0), so remove mentions of it.
Prevent too long user name or password from client
In most cases, this wouldn't work anyway, because for example the user
wouldn't be found in pgbouncer, since userlist.txt doesn't permit too
long user names. But in the case of PAM there was no such check, so
too long user names could be added by add_pam_user(), which would
truncate them, and then a subsequent search using the not-truncated
name wouldn't find it, causing duplicates to be added.

Avoid 'unexpected response from login query' after a postgres reload
After a PostgreSQL reload, the backend could inform the frontend about
configuration changes by sending some ParameterStatus messages
together with the usual login query response. These messages can be
safely ignored in the login query response handler.

Do not wait server_login_retry for next connect if cancellation succeeds
If postgres restarts while there are N cancellations in the queue,
pgbouncer is currently unavailable for at least N*server_login_retry
because it uses every new connection for one queued cancellation and
then waits server_login_retry before opening a new connection because
the last_connect_failed flag is still set to 1. This can lead to
prolonged downtime.
This changes fixes the issue by introducing a last_login_failed flag.
The last_connect_failed is now reset when a cancellation succeeds, such
that launch_new_connection no longer waits if pgbouncer manages to
connect, but has queued cancellations. The last_login_failed flag has
the same semantics as the last_connect_failed flag had previously, such
that check_fast_fail still rejects connections when there are no servers
available and the last login failed.

test.sh: Sort out netcat zoo
The previous code distinguished between Linux and non-Linux netcat.
This didn't stand the test of time, since Linux distributions now ship
multiple variants of netcat and other operating systems also provide
multiple options. So instead try to detect the variant from the help
output. Also, the previous uses of the -q and -w options behaved
strangely with some versions and/or were inconsistent with the
documentation. So abandon those options and just rely on the existing
killall call.

hopefully most configurations.

doc: Small improvement in quick start

If we fail to calloc the rule buffer, going to failed: will deref
rule via the rule_free() call. Avoid by returning false directly

If the fopen() call fails parse_namefile() frees the filename buffer
