9b350f9ecc cmake: some formatting fixes
Do not include bootloader in flash target when secure boot is enabled.
Emit signing warning on all cases where signed apps are enabled (secure
boot and signed images)
Follow convention of capital letters for SECURE_BOOT_SIGNING_KEY
variable, since it is
relevant to other components, not just bootloader.
Pass signing key and verification key via config, not requiring
bootloader to know parent app dir.
Misc. variables name corrections

9c6bec203d HTTP Server : Close new session immediately if open_fn fails
open_fn() was introduced in the context of HTTPS server, as a configurable callback function that is called by the HTTP server, on every newly created socket. It is responsible of allocating resources for per session transport security.

Earlier, if open_fn were to fail, the newly created socket would be closed by the server but the corresponding entry, for the now invalid socket, will remain in the internal socket database until that invalid socket is detected due to error when calling select(). Because of this delayed closing of sockets, the HTTPS server would quickly face shortage of available sessions when a lot of SSL handshake errors are happening (this typically occurs when a browser finds that the server certificate is self signed). This changes in this MR fix this issue by clearing up the socket from internal database, right after open_fn fails.

ffad8b27a3 esp_http_server : Allow binding to same address and port upon restarting server without delay
Issue : Restarting the server without 30sec delay between httpd_stop() and httpd_start() causes EADDRINUSE error

7e676c1055 esp_http_server : Only accept new connections if server has capacity to handle more
This fix prevents HTTP server from accepting new connections when the total count of connected
sockets has reached the max_open_sockets limit set during configuration. The pending connections
are kept in backlog until atleast one of the connected sockets is closed. The maximum number of
connection requests that can kept in backlog is specified as backlog_conn configuration option.
Note that this modification has no effect when LRU purge is enabled.

Also added sanity check on setting for max_open_sockets during configuration.

7f1047847a HTTP Server: Added ability to select core
The task that runs the HTTP server can now be pinned to a particular core by setting `core_id`
in the HTTP server configuration.  By default, the core is set to `tskNO_AFFINITY`, meaning
it can run on any core.

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.

6091021e83 unity: separate common and IDF specific functionality
New unity component can be used for testing other applications.
Upstream version of Unity is included as a submodule.
Utilities specific to ESP-IDF unit tests (partitions, leak checking
setup/teardown functions, etc) are kept only in unit-test-app.
Kconfig options are added to allow disabling certain Unity features.

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
