If OPENSSL_MAX_TLS1_2_CIPHER_LENGTH is set then limit the size of client
ciphersuites to this value. A value of 50 should be sufficient.

Document workarounds in CHANGES.

Some servers hang when presented with a client hello record length exceeding

Localize client hello extension parsing in t1_lib.c

enabled instead of requiring an application to hard code a (possibly
inappropriate) parameter set and delve into EC internals we just

Tidy some code up.

Don't allocate a structure to handle ECC extensions when it is used for
default values.

Make supported curves configurable.

Add ctrls to retrieve shared curves: not fully integrated with rest of
ECC code yet.

Fix memory leaks in 'goto err' cases.
