990af312d1 HTTP Server : Fix for tolerating LF terminated headers
List of changes:
* When parsing requests, count termination from LF characters only
* Correct memcpy() length parameter in httpd_unrecv() (pointed out by jimparis in GitHub issue thread)
* Use ssize_t to store results of length subtractions during parsing
* Modify some comments to reduce ambiguity

Closes https://github.com/espressif/esp-idf/issues/3182

28412d8cb6 http_server : Added feature for invoking user configurable handlers during server errors
Added APIs :
  * httpd_resp_send_err()        : for sending HTTP error responses for error codes given by httpd_err_code_t. It uses TCP_NODELAY option to ensure that HTTP error responses reach the client before socket is closed.
  * httpd_register_err_handler() : for registering HTTP error handler functions of type httpd_err_handler_func_t.

The default behavior, on encountering errors during processing of HTTP requests, is now to send HTTP error response (if possible) and close the underlying socket. User configurable handlers can be used to override this behavior for each error individually (except for 500 Internal Server Error).

Also fixed some typos.

107f52c4fc HTTP Server : Add helper APIs for sending string content
Note : In future consider deprecating usage of -1 for setting
buffer length equal to string length in APIs httpd_resp_send()
and httpd_resp_send_chunk()

9a9d18e466 esp_http_server : APIs renamed and context get/set implementations fixed
* http_sess_set_*_override APIs are now the only ones available to set custom recv/send/pending functions
* Fixed side effects to using http_sess_set/get_context inside URI handlers

a10fc02dd9 esp_http_server improvements to allow adding transport layer encryption
Changes:
- renamed `httpd_free_sess_ctx_fn_t` to `httpd_free_ctx_fn_t`
- added a `httpd_handle_t` argument to `httpd_send_func_t` and `httpd_recv_func_t`
- internal function `httpd_sess_get()` is no longer static, as it's used in other
  files besides httpd_sess.c

Bug fixes:
- removed a trailing semicolon from `HTTPD_DEFAULT_CONFIG()`
- fixed issue with failed `select()`, now it automatically closes invalid sockets
  instead of shutting down the entire server

New features:
- `httpd_resp_send()` and `httpd_resp_send_chunk()` now accept -1 as length to use
  `strlen()` internally
- added `httpd_sess_set_ctx()` to accompany `httpd_sess_get_ctx()`
- added a "transport context" to the session structure (next to user context)
- added `httpd_sess_{get,set}_transport_ctx()` to work with this transport context
- added "global user context" and "global transport context" stored in the server
  config (and then the handle); supports a user-provided free_fn
- added a "pending func" to e.g. check for data in the transport layer receive
  buffer
- added functions `httpd_set_sess_{send,recv,pending}_override()` that target
  a session by ID (i.e. not using a request object)
- added `httpd_set_pending_override()`
- added a "open_fn" and "close_fn" - functions called when creating and closing
  a session. These may be used to set up transport layer encryption or some other
  session-wide feature
