ede477ea65 paritition_table: Verify the partition table md5sum when loading the app
Additionally, always enable the partition MD5 check if flash encryption is on in
Release mode. This ensures the partition table ciphertext has not been modified
(CVE-2021-27926).

The exception is pre-V3.1 ESP-IDF bootloaders and partition tables, which
don't have support for the MD5 entry.

b64fd872bc Allow esptool's download stub to be disabled by other options and applications

abd6d40796 secure boot: Ensure mbedTLS enables ECDSA if signatures are checked in app
and all ECDSA to be disabled if secure boot is not enabled

Previously if ECDSA disabled in config then secure_boot_signatures.c would
fail to build (whether or not secure boot was enabled).

To avoid breaking apps that might be using the signature scheme with custom OTA
without enabling secure boot signatures in config, this change just disables
this functionality if unavailable in mbedTLS config.

43393cf4d1 bootloader: Support for skipping validation upon wake from deep sleep
This saves time when waking up from deep sleep, but potentially decreases
the security of the system.  If the application able to modify itself
(especially areas that are loaded into RAM) in flash while running
without crashing or is modifies the cached bits of information about
what was last booted from the bootloader, this could cause security
issues if the user does a "deep sleep reset" since the full validation
is skipped.

57b601ab7f secure boot: Pad to avoid data after the signature mapping into the address space
Because address space is mapped in 64KB pages, it was possible for unauthenticated data after the
app .bin to become mapped into the flash cache address space.

This problem is solved by 2 changes:

* "esptool elf2image --secure-pad" will pad the image so that the signature block ends close to the
  64KB boundary. Due to alignment constraints it will be 12 bytes too short after signing (but
  with flash encryption, these 12 bytes are still encrypted as part of the last block and can't be
  arbitrarily changed).
* By default, secure boot now requires all app partitions to be a multiple of 64KB in size.
