setup: require that Python has TLS 1.1 or TLS 1.2
This ensures that Mercurial never downgrades the minimum TLS version from
TLS 1.1+ to TLS 1.0+ and enables us to remove that compatibility code.
It is reasonable to expect that distributions having Python 2.7.9+ or having
backported modern features to the ssl module (which we require) have a OpenSSL
version supporting TLS 1.1 or TLS 1.2, as this is the main reason why
distributions would want to backport these features.
TLS 1.1 and TLS 1.2 are often either both enabled or both not enabled.
However, both can be disabled independently, at least on current Python /
OpenSSL versions.
For the record, I contacted the CPython developers to remark that
unconditionally defining ssl.PROTOCOL_TLSv1_1 / ssl.PROTOCOL_TLSv1_2 is
problematic:

sslutil: check for OpenSSL without TLS 1.0 support in one case
It can only happen if supportedprotocols gets fixed to contain only correct
items (see the FIXME above in the file).

sslutil: don't set minimum TLS version to 1.0 if 1.2 but not 1.1 is available
This case isn't very likely, but possible, especially if supportedprotocols
gets fixed to contain only correct items (see the FIXME above in the file).

sslutil: fix names of variables containing minimum protocol strings
When working in this module, I found it very confusing that "protocol" as a
variable name could mean either "minimum protocol string" or an exact version
(as a string or ssl.PROTOCOL_* value). This patch prefixes variables of the
former type with "minimum".

sslutil: stop returning argument as third return value of protocolsettings()
The third return value was always the same as the argument.

tests: stop checking for optional, now impossible output
In 7dd63a8cb1ee, the code that could output that line was removed.

githelp: add some minimal help for pickaxe functionality
Due to a conversation in work chat, I realized this is actually pretty
well-hidden in Mercurial.

tests: remove "sslcontext" check
Now that we require the presence of ssl.SSLContext in setup.py, the check
would always return `True`.
