Andrew Tridgell 4197fdeb2a AP_HAL: fixed bug in vsnprintf()
we need to return the number of bytes that would have been printed if
the buffer was big enough to support use cases such as vasprintf()
which needs to know how many bytes to allocate

Andrew Tridgell 11c123e4da AP_HAL: added persistent_data structure
this is a much simpler way to save data for a watchdog reset

Peter Barker 33e3d6e254 AP_HAL: Util: make vsnprintf and snprintf always null-terminate
The C++ standard indicates these functions always return a
null-terminated string.  We should rename these functions if we're not
going to conform to the standards.

From https://en.cppreference.com/w/cpp/io/c/vfprintf :

"Writes the results to a character string buffer. At most buf_size-1
characters are written. The resulting character string will be
terminated with a null character"

We are still not standards-compliant in the case a length of 0 is passed
in, returning 0 where we should return the space that would be required
to store the formatted string.

Gustavo Jose de Sousa 0456eccca8 AP_HAL: standardize inclusion of libaries headers
This commit changes the way libraries headers are included in source files:

 - If the header is in the same directory the source belongs to, so the
 notation '#include ""' is used with the path relative to the directory
 containing the source.

 - If the header is outside the directory containing the source, then we use
 the notation '#include <>' with the path relative to libraries folder.

Some of the advantages of such approach:

 - Only one search path for libraries headers.

 - OSs like Windows may have a better lookup time.
