gps file dump: re-implement with an uORB topic & write to the log file ( #4987 )
...
Drawbacks of the previous method: when writing to the SD card, there are
high delays in the write() call of several 100ms, every now and then. The
frequency and length of these events depend on:
- SD card
- used logger bandwidth
- bandwidth of gps data (RTCM)
Since the whole gps thread was blocked during this period, it lead to
gps timeouts and lost module.
What we do now is: publish an orb topic with queuing. This makes it async
and the logger takes care of buffering. This means it's best to:
- use high logger rate
- use large logger buffer
- reduce logger bandwith by disabling unused topics

logger: free up ~200B stack size
...
we now use the already existing buffer for logging messages, which is
allocated on the heap.
In fact, stack usage was too high before this, now it's ok again.

logger: don't use uint8_t buffer[msg_size]; (it's C99 not C++)
...
Also, it's not clear where the allocation was. It looks like it was on
the heap, but the compiler could decide to put it on the stack. This is
very bad for us because we use fixed size stacks with tights bounds. So if
a user specifies a large topic to log, it could have crashed.
Now the allocation is on the heap and the user can specify any size of
topic to log (as long as there is enough memory).

orb structs: add padding bytes to align the structs where necessary
...
This is required for the logger, we just manually add the padding bytes
what would otherwise be done by the compiler. Additionally we reorder
the fields by type, so that padding is only necessary for nested types.
