Bug 1394: Document how to do per host conn limits
Since the max connections per host setting is computed and enforced
in the master listening process before the fork, there is no easy
way to get an accurate connection count once the Proxy Protocol
negotiation has been done (i.e. in a child process, after the
fork). Rather than try to use a shared mmap file using CAS in the
children to manipulate it, we just advise of a crude version of
max connections per IP be achieved by using ratelimit per_conn in
the connect ACL.

Bail configuration on missing package
If we're configured to use pkg-config (or pcre-config) and the tool is
not available or does not know about the package we ask for, that should
be a fatal configuration error.
We should not silently ignore the missing package, then try to compile,
and have missing header warnings from the compiler. Eg, if we're told
to support GSASL, we'll try to compile the client code, and without
compiler flags, we'll either fail to compile (missing headers) or fail
to link, which obscures the source of the errors.
This change will only break people who had builds set to have Exim
depend upon non-existent packages, and that _needs_ to break.

Report OpenSSL build date too.
Adjust `-d -bV` output for OpenSSL to include library build date.
Some OS packagers have backported heartbleed security fixes without
changing anything in the reported version number. The closest we can
get to a reassuring sign for administrators is to report the OpenSSL
library build date, as picked by the library which Exim is using at run
time.
```
Library version: OpenSSL: Compile: OpenSSL 1.0.1g 7 Apr 2014
Runtime: OpenSSL 1.0.1g 7 Apr 2014
: built on: Mon Apr 7 15:08:30 PDT 2014
```
For comparison, the version information for OpenSSL on Ubuntu (where
Exim is by default built with GnuTLS, but this provides for context for
comparison):
```
$ openssl version -v -b
OpenSSL 1.0.1 14 Mar 2012
built on: Mon Apr 7 20:33:29 UTC 2014
```
GnuTLS: the closest I can find to a runtime value is the call we are
already making; if an OS vendor patches GnuTLS without changing the
version which would be returned by `gnutls_check_version(NULL)` then the
sysadmin is SOL and will have to explore library linkages more
carefully.
