961f59ff57 mbedtls: Don't unnecessarily grow the result of a hardware bignum operation
Avoids growing the result of hardware bignum operations
(particularly for multiplication)

Fixes bugs where some Elliptic Curve operations fail or corrupt memory,
as they assume length of the number is never greater than the number of
non-zero limbs.

Includes some general refactoring to standardize terminology.

Closes https://github.com/espressif/esp-idf/issues/1556

Fixes TW12984

Adds test cases for both these issues.

8f80cc733d soc: Change DPORT access
When two CPUs read the area of the DPORT and the area of the APB, the result is corrupted for the CPU that read the APB area.
And another CPU has valid data.

The method of eliminating this error.
Before reading the registers of the DPORT, make a preliminary reading of the APB register.
In this case, the joint access of the two CPUs to the registers of the APB and the DPORT is successful.

254e29aca4 mbedtls: update usage of deprecated mbedtls_shaX APIs
The following mbedTLS APIs have been deprecated and replaced with the
new ones which return error codes:

mbedtls_shaX_starts -> mbedtls_shaX_starts_ret
mbedtls_shaX_update -> mbedtls_shaX_update_ret
mbedtls_shaX_finish -> mbedtls_shaX_finish_ret
mbedtls_shaX_process -> mbedtls_shaX_internal_process

Update hardware implementations of SHA functions, and other IDF
components which used above functions, to use new versions.

* Disables 3DES, Camellia, Blowfish, RC4, RIPEMD160, SSLv3, TLS-PSK modes, DTLS by default
* Saves about 40KB from the default TLS client code size
* Defaults no longer get "Bad" howsmyssl.com rating (no more vulnerable 3DES)
  (ping https://github.com/espressif/arduino-esp32/issues/575 )
* Allows up to another 20-30KB code size to be trimmed without security
  implications if using DER formatted certificates, RSA ciphersuites only,
  etc.
* Can save up to another 8KB by setting the TLS Role to Server or Client only.

a523aa3ef5 mbedtls port: Fix detection of EWOULDBLOCK/EAGAIN with non-blocking sockets
Since mbedtls_net_errno is reset by fcntl, it is reset after calling
net_would_block, so the call to mbedtls_net_errno in mbedtls_net_recv
and mbedtls_net_send will always get back 0. This change propagates
the value returned by mbedtls_net_errno up through net_would_block,
to allow the correct error value to be used and avoid a redundant
call to mbedtls_net_errno.

bf57594ebe Merge branch 'feature/intr_alloc' into 'master'
Add dynamic interrupt allocation mechanism

This adds:
- Dynamic allocation of interrupts. Pass it the features of the interrupt you want, it'll set you up with an int.
- Shared interrupts. Enables multiple peripheral drivers to use the same interrupt. 
- Marking what interrupts are fully executable from IRAM; if an int isn't marked like that it will get disabled once flash cache gets disabled.

Also:
- Modifies driver to be in line with these changes

79646f41b5 Fixes for stdlib.h inclusion
Refs:
http://esp32.com/viewtopic.php?f=13&t=550
http://esp32.com/viewtopic.php?f=13&t=551

rmt.c should include stdlib.h for malloc, esp_bignum,c &
https_request_main.c for abort().

FreeRTOSConfig.h is only including stdlib if
CONFIG_FREERTOS_ASSERT_ON_UNTESTED_FUNCTION is set. However, it is
included for abort() so needs to be included whenever
CONFIG_FREERTOS_ASSERT_FAIL_ABORT is set.

This change includes unconditionally in FreeRTOSConfig.h. This is to
avoid this kind of bug where compiler errors are dependent on config. I
suggest we don't change this to be more selective until we have 'make
randomconfig' style tests in CI.
