Xia Xiaotian 63019689d6 Coexist: fix some coexist bugs
1. Fix high beacon and broadcast packets loss ratio of WiFi to make
   MDNS test pass.
2. Improve stability of WiFi performance with a little
   sacrifice of throughput.
3. Improve BLE advertising and connection performance with dynamic
   priority. It sacrifices a little WiFi throughput, but achieves balance
   between WiFi and Bluetooth.

Nachiket Kukade 9ec363a25d wpa_supplicant: Make internally used crypto headers private
A lot of internally used crypto headers are publicly includeable
in user projects. This leads to bug reports when these headers
are incorrectly used or the API's are not used as intended.

Move all crypto headers into private crypto src folder, also move
crypto_ops into Supplicant to remove dependecy on crypto headers.

Closes IDF-476

wpa_supplicant is using MbedTLS API's for crypto algorithms. For

with 'fast_'. Remove these and use flag USE_MBEDTLS_CRYPTO
instead to separate modules calling MbedTLS API's from native
implementation.

Renz Christian Bagaporo 54ef60f26b component: revert some of the dependency corrections
!4452 and !4897 made some ill-advised corrections to dependency info;
revert those in this MR. Handling pre-built binaries as imported
libraries is retained, however.
2019-06-11 18:09:26 +08:00
Renz Christian Bagaporo 3882e48e8a cmake: use new signature form of target_link_library to link components
!4452 used setting LINK_LIBRARIES and INTERFACE_LINK_LIBRARIES to link
components built under ESP-IDF build system. However, LINK_LIBRARIES does
not produce behavior same as linking PRIVATE. This MR uses the new
signature for target_link_libraries directly instead. This also moves
setting dependencies during component registration rather than after all
components have been processed.

The consequence is that internally, components have to use the new
signature form as well. This does not affect linking the components to
external targets, such as with idf_as_lib example. This only affects
linking additional libraries to ESP-IDF libraries outside component processing (after
idf_build_process), which is not even possible for CMake<v3.13 as
target_link_libraries is not valid for targets not created in current
directory. See https://cmake.org/cmake/help/v3.13/policy/CMP0079.html#policy:CMP0079
