Simplify and rename SSL_set_rbio() and SSL_set_wbio()

SSL_set_rbio() and SSL_set_wbio() are new functions in 1.1.0 and really
should be called SSL_set0_rbio() and SSL_set0_wbio(). The old
implementation was not consistent with what "set0" means though as there
were special cases around what happens if the rbio and wbio are the same.
We were only ever taking one reference on the BIO, and checking everywhere
whether the rbio and wbio are the same so as not to double free.

A better approach is to rename the functions to SSL_set0_rbio() and
SSL_set0_wbio(). If an existing BIO is present it is *always* freed
regardless of whether the rbio and wbio are the same or not. It is
therefore the callers responsibility to ensure that a reference is taken
for *each* usage, i.e. one for the rbio and one for the wbio.

The legacy function SSL_set_bio() takes both the rbio and wbio in one go
and sets them both. We can wrap up the old behaviour in the implementation
of that function, i.e. previously if the rbio and wbio are the same in the
call to this function then the caller only needed to ensure one reference
was passed. This behaviour is retained by internally upping the ref count.

This commit was inspired by BoringSSL commit f715c423224.

internal pc path length cache for a given X509 structure, along with
X509_get_proxy_pathlen(), which retrieves it.

Along with the previously added X509_set_proxy_flag(), this provides
the tools needed to manipulate all the information cached on proxy
certificates, allowing external code to do what's necessary to have
them verified correctly by the libcrypto code.

Add X509_STORE lock and unlock functions

Since there are a number of function pointers in X509_STORE that might
lead to user code, it makes sense for them to be able to lock the
store while they do their work.
