- Always process ALPN (previously there was an early return in the
  certificate status handling)
- Don't send a duplicate alert. Previously, both
  ssl_check_clienthello_tlsext_late and its caller would send an
  alert. Consolidate alert sending code in the caller.

If the SSL_SESS_CACHE_NO_INTERNAL_STORE cache mode is used then we weren't
removing sessions from the external cache, e.g. if an alert occurs the
session is supposed to be automatically removed.

Don't call strncpy with strlen of the source as the length. Don't call
strlen multiple times. Eventually we will want to replace this with a proper
PACKET style handling (but for construction of PACKETs instead of just
reading them as it is now). For now though this is safe because
PSK_MAX_IDENTITY_LEN will always fit into the destination buffer.

This addresses an OCAP Audit issue.

In preparation for splitting this function up into smaller functions this
commit reduces the scope of some of the variables to only be in scope for
the algorithm specific parts. In some cases that makes the error handling
more verbose than it needs to be - but we'll clean that up in a later
commit.
