5a88f90a33 soc/rtc: warn if detected XTAL frequency does not match configured one
Since 9a8c0392, XTAL frequency is set to 40MHz by default, and users
of 26MHz boards need to select 26MHz manually. Most users are not aware
of this change, and existing getting started guides do not mention that
XTAL frequency needs to be set for some boards. So users are left with
garbage output from UART without any clue what to check.

This change adds a warning in case specific XTAL frequency was set, and
it does not match automatically detected one. This should help users
fix the issue.

1cd2ce2471 bootloader: Fix regression preventing OTA updates
Regression introduced in 43e231c.

Thanks to @yanbe for pointing out issue in https://github.com/espressif/esp-idf/pull/955

This is a different fix, tries to keep the behaviour that 43e231c was aiming to correct (unnecessarily testing an
invalid slot more than once.)

43e231c916 bootloader: Don't unnecessarily test OTA app slots more than once per boot
Would loop more than once through each OTA possibility, but really only
needs to try each slot once.

5eef5e7a5d bootloader: Fallback if OTA data is invalid
Make bootloader more robust if either OTA data or some OTA app slots are corrupt.

17adb40ca8 bootloader: Calculate SHA256 hash of image on every boot
Makes app image booting more reliable (256-bit rather than 8-bit verification.)

Some measurements, time to boot a 655KB app.bin file and run to app_main() execution.

(All for rev 1 silicon, ie no 340ms spurious WDT delay.)

80MHz QIO mode:
before = 300ms
after = 140ms

40MHz DIO mode:
before = 712ms
after = 577ms

40MHz DIO mode, secure boot enabled
before = 1380ms
after = 934ms

(Secure boot involves two ECC signature verifications (partition table, app) that take approx 300ms each with 80MHz CPU.)

0c8888d68f bootloader: Combine loading from flash & verifying to save boot time
Still needs updating to account for secure boot.

d664e32394 build system: Use component.mk for all components, refactor bootloader build
For config-only components, component.mk should now contain "COMPONENT_CONFIG_ONLY := 1"

Also refactored some of the generation of linker paths, library list. This required cleaning up the way the bootloader
project works, it's now mostly independent from the parent.
