spi_flash_enable_interrupts_caches_and_other_cpu function used to enable
non-IRAM interrupts after giving up flash operation lock, which would
cause problems if another task was waiting on the lock to start a flash
operation. In fact, non-IRAM interrupts should be re-enabled before the
task scheduler is resumed. Otherwise non-pinned task can be moved to the
other CPU due to preemption, causing esp_intr_noniram_enable to be
called on the other CPU, causing an abort to be triggered.

Delete option to select core timer 2 as a FreeRTOS tick source
Core timer 2 is unusable for FreeRTOS ticks because it triggers a high-level interrupt. This MR deletes the option to select it.

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.

1. add openssl option at menuconfig
2. remove SSL_ERR to reduce complexity
3. add more functions about debugging and assert
According these, our coders and customers may use and debug the OpenSSL code easily.
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.
These functions are marked as inline and are called from functions which are in IRAM.
In release (-Os) builds, the compiler may decide not to inline these functions.
Placing these functions into IRAM explicitly works around this.

vfs: implement reading from UART
This change adds support for reading from the UART FIFO via the `stdin`.
Useful for simple cases when handling lots of data is not a requirement (e.g. command prompts operated by humans).
`\r\n` -> `\n` conversion is guided by the existing `CONFIG_NEWLIB_STDOUT_ADDCR` configuration option.
