nvs: speed improvement and erase APIs
NVS initialization speed issue raised in https://ezredmine.espressif.com/issues/6881 has been addressed for single core mode through optimization of `spi_flash_*` routines. This MR addresses same issue for dual core mode.
- An index table is added at Page level, it allows doing fast search of item index based on key name and namespace. This heavily reduces the number of flash reads.
- Write operations are batched when writing/erasing long variable-length values (str and blob). This gives a 33% reduction in the number of writes for a 64-byte value, 50% reduction for a 96-byte value.
- Add optional (configurable via menuconfig) perfomance counters for spi_flash APIs
With these changes, total init time for NVS goes down from 2 seconds to 140 ms.
Additional RAM usage is 128-640 bytes per page, depending on content. Typical RAM usage for current use case (storing wifi configuration parameters) is 256 bytes.
This change also exposes APIs to erase single key or the whole namespaces, needed for https://ezredmine.espressif.com/issues/6769.

Clean up warnings and remove unused parts of FreeRTOS
For third party components (lwip and expat), compilation flags are adjusted to silence existing warnings (i have manually checked that all warnings are benign).
In components/esp32, replaced use of WIFI_DEBUG with ESP_LOG functions.
Additionally prvLockQueue/prvUnlockQueue have been removed, dragging some other bits of FreeRTOS along.
Original issue: https://github.com/espressif/esp-idf/issues/18

BT support
Initial version of BT support.
BT and WiFi are mutually exclusive at this point, so we have a new option to select which stack is used.
Precompiled BT libraries are added as a submodule.

For third party components (lwip and expat), compilation flags are adjusted to silence existing warnings (i have manually checked that all warnings are benign).
In components/esp32, replaced use of WIFI_DEBUG with ESP_LOG functions.
Only remaining warning is in FreeRTOS queue.c, and it may be a useful one.
Introduces new internal function, Page::alterEntryRangeState, which gathers changes to multiple elements of entry state table into a single write, provided that these changes fall into a single word. This allows changing state of up to 16 entries in a single write.
Also adds new function, writeEntryData, which writes the whole payload of SZ and BLOB type entries in one go, instead of splitting it into multiple 32-byte writes.
This reduces number of writes required for SZ and BLOB entries.

peripheral structure headers: move volatile keyword from members to typedef
Adding -fstrict-volatile-bitfields to the CFLAGS/CXXFLAGS. Without this, gcc tries to access bitfields using the smallest possible methods (eg l8i to grab an 8-bit field from a 32-bit). Our hardware does not like that. This flag tells gcc that if a bitfield is volatile, it should always use the type the field is defined at (uint32_t in our case) to size its access to the field. This fixes accessing the hardware through the xxx_struct.h headers.

Add logging library
Logging library, intended to be used across other components.
Uses design similar to Android NDK logging APIs and allows for both compile time and run time filters, similar to logcat.
Also includes cleanup of cpu_startup.c — i was changing some logging output in this file so decided to re-format it and reduce code duplication.

make SO_REUSE configurable via menuconfig
SSC expects SO_REUSE to be off by default.
Trivial change, moving this option to menuconfig.
This should also (finally!) fix failing tests in master.
