roughly 10K bytes below the 1MiB limit

With GCC 4.9 the binary is to large for the flash memory.
This is why we disabled LPE on that platform.

-closes #5862

This update is needed after changes in
https://github.com/ATLFlight/cross_toolchain/pull/10.

AeroFC is updated by Aero board using the UART between AeroFC
and Aero board.

This script will copy firmware and px_uploader.py to Aero board and run
px_uploader.py with the correct paremeters. User only needs to have a
network connection (Ethernet over USB or WiFi) with Aero board to update
AeroFC firmware. The IP/hostname can be given by AERO_HOSTNAME
environment variable.

This disables the following modules to save flash:
- mpu9250 driver because the MPU9250 is rarely used on Pixhawks
- Snapdragon RC PWM passthrough which is rarely used and definitely a
  special/custom configuration. Also, it will soon be obsolete with the
  upcoming PWM support on Snapdragon.

The generated binary hash was off by one.

This updates cmake_hexagon and cmake_hexagon inside DriverFramework
which fixes somethine about rpcmem.a and the double linking issue.

These are some changes that I needed to compile
most of the unsupported targets.

After this all (make list_config_targets) compile
for me except: posix_eagle_muorb, posix_sdflight_default
and qurt_eagle_legacy_driver_default.

app.h, generated from app.h_in, has unnecessary code duplication
and isn't a header file (it defines globals, static functions
and doesn't have a header guard, moreover, it has a 'using namespace
std;'). Because of this, a real headerfile that declares the stuff
defined in apps.h was missing leading to even more code duplication:
scattered forward declarations in .cpp files and an often repeated
type of std::map<std::string, px4_main_t>.

This patch moves cmake/qurt/apps.h_in to src/platforms/apps.cpp.in
(with some changes) and removes cmake/posix/apps.h_in.
Then src/platforms/apps.cpp.in is split into src/platforms/apps.cpp.in
and src/platforms/apps.h.in, splitting declarations from definitions.

A typedef is defined for the map (apps_map_type).

The main difference between cmake/posix/apps.h_in and
cmake/qurt/apps.h_in was that the first defined a global 'apps',
while qurt stores the apps in QShell. I opted to get rid of
the global variable (which are in general evil for various reasons)
and used the API of cmake/qurt/apps.h_in where a provided 'apps'
map is initialized with a call to init_app_map. Thus removing
the existing code duplication.

The firmware binary is to large to fit into the onboard memory of the Parrot
Bebop. It could be uploaded to the emmc, but for ease of use it would be nice
to have it in /usr/bin. To strip the binary seems to be the best option right now.

The pthread linker flags were changed in c6a26415 and it was questioned in #5504 if the
exception for the Bebop is necessary. It is not, so remove those lines from the cmake
file.
