Remove sslhaf_suites.h, will be autogenerated on each build
Remove a redundant indentation
Refactoring and code tidyup in preparation for future additions

* Renamed a number of variables in sslhaf_cfg_t in preparation for more
  variables in future.  Also some name changing:
    cslen -> suites_len
    compression_methods -> tcompmethods as it is a printable string
    extensions -> textensions as it is a printable string
* A number of stack variables in decode_packet_v3_handshake are renamed
  in order to make their purpose clearer thus code flow more readable.
  Using names such as: msg_len, section_to_go, sub_section_to_go
* Reuse some counter/offset variables as their naming eg. section_to_go
  as there may be many sections in a message, and this usage helps the
  reader to understand the code
* Standardise on usage if array indexing instead of deref pointer +
  offset when combining multiple array elements into a numeric value,
  for example: *(p + 1) -> p[1], numerous usages of the * operator
  remain where they are trivial
* mylen -> msg_to_go, make this variable follow the progress of 'p'
  more closely, eg. when p is incremented, decrement msg_to_go straight
  away instead of a large decrement at the end of a while loop
New pluggable function for freeing snprintf buffers, default constructors

* Because the allocator used to allocate memory in snprintf_fn may be
  different from the one used in alloc_fn, allow a special free function
  for snprintf buffers.
  Signature is same as free_fn, so user may just reuse that as is the case
  in the default pluggable functions.
* Add default constructors for sslhaf_cfg_t, which use default pluggable
  functions
Support deeper inspection of TLS, particularly SNI extension

With this feature comes a number of structural changes.

* sslhaf_cfg_t::suites now becomes an array of pointers to a
  suite description object that contains a nice name field and a
  key length field.  This table is auto generated from the
  suites.csv document located in the source tree.
* sslhaf_cfg_t::compression_methods is now an array of objects
  describing the compression method, as of now just the id field
* sslhaf_cfg_t::extensions is an array of objects describing the
  extension, with more detail provided for certain supported
  extensions, as of now just SNI
* streamlined data types used in sslhaf_cfg_t and parsing code,
  in particular using uint16_t or uint8_t for sizes where the
  sizes are sourced from two or one bytes
* standardised use of offset variables to aid code readability.
  offset variables are prefixed with '_to_go' indicating the
  number of bytes remaining in their respective domain
* standardised coding style of bounds and error checking to aid
  readability and resilience to coding errors
* reduced return codes to a smaller set.  additional error info
  added to sslhaf_cfg_t as 'last_error_' fields.  Original OK
  return code remains same, but all errors are now < 0.
* SSLHAF_AGAIN error code added as a special non fatal error code
  to indicate requirement for more data, will add support for
  incremental addition of data in future.
Include sslhaf/sslhaf_suites.c in .gitignore
Support fragmented data

* Allow multiple calls to sslhaf_decode_buffer containing incremental
  amounts of TLS message data.  The return value will be SSLHAF_AGAIN
  as long as there is not enough data to process a message.
* User is provided with two new statistics: input_used_session and
  input_used_total, indicating how much valid protocol data was
  used for parsing in the previous call to sslhaf_decode_buffer, and
  in all calls to sslhaf_decode_buffer.
* Method of buffering is simplistic at this stage. TODO: implement a
  better way of doing this, perhaps using bulk pre-allocations, or
  finish the pagebuf object.
Update EXTRA_DIST

Thanks to Mathieu Bridon <bochecha@fedoraproject.org> for this fix
Free resources of each server name in the server_names list
Eliminate warnings.
Add support for logging the entire Client Hello message.
Use the protocol version from Client Hello

Because some clients don't always put the best version in the
record layer packets.
Fix for Apache 2.4.x.
Add create_strings flag

To indicate a users requirement for saving printable copies of
handshake data
