Since the FRAM and the baro are on the same bus on the Pixracer, we
currently need to lock down everything (instead of just this SPI bus)
for the time when the params are written.
Therefore, we need to keep this locking as short as possible.
This change makes the locking even shorter by moving all param_get and
param_name and param_size calls out of the lock.
There was the case where a param was changed on the Linux side but the
change did not get saved on the DSP side because the param was not in
the local list of changed params on the DSP side. On save, the param
index is now refreshed, and param_get is called on all params that have
changed. This is a hacky workaround but resolves the problem for now.
The recent workaround to flag all params as used did not include
param_for_used_index(). However, this function got used in the case if
one param had not been received by QGC and was requested by its index.
On Snapdragon we can't yet use the "used" mask for parameters and
therefore need to send all of them down to the ground station. All
params were set to used in an earlier commit but the count and index
function didn't reflect this change. This is fixed now, therefore we can
successfully receive all params in QGC.
This is a workaround for the fact that the used information is not
shared between the ADSP and the Linux side on the Snapdragon. By
flagging all params used, we can at least receive them on QGC.
Code that was previously out of tree that was #if 0, is now #ifdef __PX4_QURT.
These changes were required for flight using the qurt build.
Changes include code cleanup for shmem_posix.c.

Use a struct to contain all the parameters so the ordering in
memory is not machine dependent.
Add number of parameters to the param struct. The struct actually
allows direct accessing by the member name if desired.

In nuttx the mode parameter to open is not required but in Linux,
and per the POSIX spec, mode is required if the O_CREAT flag is
passed.
The mode flags are different for NuttX and Linux so a new set of
PX4 defines was added:
PX4_O_MODE_777 - read, write, execute for user, group and other
PX4_O_MODE_666 - read, and write for user, group and other
PX4_O_MODE_600 - read, and write for user

Set a default path relative to current dir for the posix target.
Running make posixrun will create the required directoroes and then run
mainapp from its build location.
PX4_ROOTFSDIR is set to nothing for nuttx.
