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.

75d6fdf73c newlib locks: Fix _lock_init() & _lock_init_recursive() failing to initialise a lock
If scheduler was running, and lock was an automatic variable (ie stack-allocated) to be initialised by _lock_init*,
initialisation could be skipped if the lock variable was non-zero (and lock would be left invalid).

In other cases the lock is statically initialised to zero by __LOCK_INIT*

8ccb2a4990 esp32: make time monotonic across resets
Small changes to clock calibration value will cause increasing errors
the longer the device runs. Consider the case of deep sleep, assuming
that RTC counter is used for timekeeping:
- before sleep:
   time_before = rtc_counter * calibration_val
- after sleep:
   time_after = (rtc_counter + sleep_count) * (calibration_val + epsilon)
where 'epsilon' is a small estimation error of 'calibration_val'.
The apparent sleep duration thus will be:
time_after - time_before = sleep_count * (calibration_val + epsilon)
                           + rtc_counter * epsilon

Second term on the right hand side is the error in time difference
estimation, it is proportional to the total system runtime (rtc_counter).

To avoid this issue, this change makes RTC_SLOW_CLK calibration value
persistent across restarts. This allows the calibration value update to
be preformed, while keeping time after update same as before the update.

cc8af68244 syscalls: fix wraparound of RTC time
This change removes the erroneous cast to uint32_t (which caused time to
wrap around after 1 hour) and splits the multiplication into two terms
to remove the wraparound after 13 days.

6353bc40d7 Add support for 32k XTAL as RTC_SLOW_CLK source
- RTC_CNTL_SLOWCLK_FREQ define is removed; rtc_clk_slow_freq_get_hz
  function can be used instead to get an approximate RTC_SLOW_CLK
  frequency

- Clock calibration is performed at startup. The value is saved and used
  for timekeeping and when entering deep sleep.

- When using the 32k XTAL, startup code will wait for the oscillator to
  start up. This can be possibly optimized by starting a separate task
  to wait for oscillator startup, and performing clock switch in that
  task.

- Fix a bug that 32k XTAL would be disabled in rtc_clk_init.

- Fix a rounding error in rtc_clk_cal, which caused systematic frequency
  error.

- Fix an overflow bug which caused rtc_clk_cal to timeout early if the
  slow_clk_cycles argument would exceed certain value

- Improve 32k XTAL oscillator startup time by introducing bootstrapping
  code, which uses internal pullup/pulldown resistors on 32K_N/32K_P
  pins to set better initial conditions for the oscillator.

90c43ea95e newlib: fix register used for DPORT/RTC bug workaround
While there was no register at DR_REG_FRC_TIMER_BASE + 0x60, due to
peripheral address space wraparound this write actually affected one of
FRC2 registers, which is used by WiFi stack to implement legacy
ets_timer APIs.
This change uses FRC_TIMER_LOAD_REG(0) instead, which can be set to
known value safely.

8c25a0fd9d time: workaround for FRC_TIMER_INT_REG write issue
In some cases (when RTC register reads are performed from the APP CPU), a write to FRC_TIMER_INT_REG may be lost on the bus.
Writing to another DPORT register immediately before or after that works around the issue.
We write one dummy value to an address which doesn’t have any register associated with it.

c47cc63489 newlib: change definition of assert for release builds
One common pattern of using assert function looks as follows:
    int ret = do_foo();
    assert(ret == 0);   // which reads as: “do_foo should never fail here, by design”
The problem with such code is that if ‘assert’ is removed by the preprocessor in release build,
variable ret is no longer used, and the compiler issues a warning about this.
Changing assert definition in the way done here make the variable used, from language syntax perspective.
Semantically, the variable is still unused at run time (as sizeof can be evaluated at compile time), so the compiler
can optimize things away if possible.

Clean up WiFi & Bluetooth config options

* Also disables compiling/linking of BT stack if Bluetooth is disabled, saves some build time.

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

1bcd90d45d Merge branch 'feature/system_apis' into 'master'
system_* APIs cleanup

This changeset is mostly about cleaning up `system_*` APIs and moving them from libcore. It has dragged a few more changes along, however.

- `system_deep_sleep` deprecated, new name is `esp_deep_sleep`
- `system_efuse_read_mac` deprecated, new name is `esp_efuse_read_mac`
- `system_read/write_rtc_mem` removed (reason: we use linker to place code/data into RTC memory now)
- `system_get_sdk_version` deprecated. Returns "master" for now. Support for compile-time and runtime version detection will be done in a separate MR.
- `system_get_time` and variations have been deprecated. `gettimeofday` should be used instead.
- `system_restart` deprecated, new name is `esp_restart`. Rewritten code to work correctly from any of the cores.
- `system_restore` deprecated, `esp_wifi_restore` should be used instead.
- `system_get_rst_info` removed (it wasn't in a header file)
- RTC library has been updated to latest version
- Logging output from `libfoo.a` goes through `foo_printf` function now, where `foo ` is any of the library names. For libraries other than rtc and phy, this is a temporary measure, until we finish switching to esp_log library and clean up all uses of printf/ets_printf.
- ESP-IDF build will fail if any of the libraries have printf/ets_printf reference.
-  Added `esp_random` function which gets values from HW RNG. I have added code which makes sure the value is not polled too often (allows at least 16 APB cycles). Also added a header file for HW RNG (just one register).
- Moved random number generation functions used by wpa library into wpa_supplicant component.

208e83def7 build system: Refactor component.mk to not need component_common.mk
New makefile component_wrapper.mk allows some variables to be set
before component.mk is evaluated. This properly fixes problems with
sdkconfig being hard to access in all phases of the build.

Including component_common.mk is no longer necessary and will print a
deprecation warning for components which use it.

- wifi event handlers: fix incorrect MAC address printed by logging statements
- move some functions out of IRAM when compiling for bootloader

Please check commit descriptions for links to issues/forum posts and more details.
