e983042af2 http_server: adds WebSocket support
This commit adds the WebSocket support for esp_http_server
library. It mainly does:

- Handling WebSocket handshake
  - Parsing HTTP upgrade request
  - Reply the upgrade request
- Receive WebSocket packets
  - Parse header, decode to a struct
  - Unmask payload (if required)
- Send WebSocket frames
- Receive WebSocket frame
- Automatic control frame handling

a6cc964a26 esp_http_server : Bugfix in parsing of empty header values
This MR is intended to fix incorrect parsing of HTTP requests when empty header values are present.

The issue is was due to asymmetric behavior of `http_parser` library, which in case of:

    non-empty header values : invokes callbacks with the pointer to the start of a value
    empty header values : invokes callbacks with pointer to the start of next header or section

Since HTTP server relies on this pointer (along with length of the value) to locate the end of a value, and replace the line terminators (CRLFs) with null characters, the second case needed to be handled correctly.

Closes IDFGH-1539

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

f28f4016cb esp_http_server: Provide apps an option to let http_server ignore sess_ctx changes
By default, if a URI handler changes the http session context,
the webserver internally clears the older context after the handler
returns. However, if applications want to change this behavior and
manage the allocation/de-allocation/freeing themselves and let the
server handle only the "socket close" case, this commit provides such
an option.

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.
