24291f7a3b Bluedroid: Do not initiate/accept connection with device having same BDADDR. 
Added BD_ADDR comparison in l2cu_lcp_allocate and removed check from
security connection request handler as it's handled in l2cu_lcp_allocate
for both connection request and create connection.

359509ccdc bt: removed esp_bt_get_mac() 
There was no need for this function as there is already a way present to
fetch own mac address. Own mac addr can be fetched by calling
controller_get_interface().

d228fc826c protocomm security1: Restart security session if SESSION_STATE_CMD0 is received 
With the introduction of cookies to track a session, it is possible that the
clients restart the provisioning on the same session, specifically when a user
cancels a current provisioning attempt. This can result in an error as the state
on the device side and client side will go out of sync.

This has now been changed such that if SESSION_STATE_CMD0 is received on
an existing session, the state is reset and flow allowed to continue.

328254c631 protocomm_httpd: Use HTTP cookies to track session 
Earlier, a "socket connection" was being considered as a protocomm "session".
However, for HTTP, we cannot expect clients to necessarily use the same
socket for all requests of a given transaction. This was indeed causing
some failures for Wi-Fi provisioning from Android phones.

So, we have introduced http cookies to track a session even if the socket
connection does not stay intact throughout the transaction.
This change is backward compatible. If the client does not use cookies, the
socket connection will be considered as the session.

6514009b8a soc esp32: Removes parentheses from RTC_MEM_xyz macros that expand directly to single numbers 
Not necessary in these cases, and prevents parens from expanding into the
assembly code added in the parent commit - a pattern which is accepted
by GCC assembler but illegal syntax for LLVM assembler.

7c5afa262d deep sleep: Calculate RTC CRC immediately before deep sleep, without using RAM 
Fix for issues where RTC FAST memory is updated as part of going into deep
sleep. Very high risk if heaps are in RTC memory - in particular task stacks
may be in RTC memory, but also other variables.

Also fixes potential concurrency problems as RTC FAST memory is not accessible
by CPU during the CRC calculation itself.

Method:
- Disable interrupts (currently for single core only, will need update for S3)
- Load all registers before calculating CRC or going to sleep
