fix language (spelling/grammar) in comments

gcc is, at best an "it", not a "he". And even then I'm afraid it
cannot feel happiness. Not when compiling C++ anyway.

TS-2365: configure max TLS record size

The client can decipher the data only once it has received a full
record over SSL. The record size can have significant impact on the
page load time performance of the application. No limitation on
record size means that clients might have to download up to 16KB
of data before starting to process them, whereas very small records
incur a larger overhead due to record framing. The suggestion is
to configure the TLS record size to fit into a single TCP segment,
this can improve page load times on browsers located over high
latency or low bandwidth networks.

TS-2413: release memory for idle SSL connections

OpenSSL tends to allocate about 50KB of memory for each connection.
Setting flag: "SSL_MODE_RELEASE_BUFFERS" can save around 34K per
idle SSL connection. This flag has no effect on SSL v2 connections,
or on DTLS connections.

TS-2397: correct formatting and fix links

add the graphviz extension to conf.py
indent the digraph so it is actually picked up by sphinx
give it a nicer name, 'g' is too generic! Give it a nicer alt text,
because otherwise we end up with the digraph code.
Consistent formatting & links.

Outstanding: TS_HTTP_REQUEST_TRANSFORM_HOOK and
TS_HTTP_RESPONSE_TRANSFORM_HOOK still need to link to the correct
constants in doc/reference

TS-2415: use standard continuations to release UrlRewrite objects

UrlRewrite uses a custom continuation to release the old object
after it is no longer needed. We can use library code for this
instead. Use new_Deleter to free the old UrlRewrite object.
