__STDC_FORMAT_MACROS changes the behavior of inttypes.h to allow
defining format macros for printf-like functions. It needs to be defined
before any include is done, otherwise due to include chains and header
guards it may not take effect.

Instead of having to define it everywhere it is used, move the define to the
build system. Also update ecl and DriverFramework submodules to deal with the
changed definitions.

Streams ordered same way in all modes.

Fixed units to be microseconds and not milliseconds.

Sdlog2 misses least updates when the CPU scaling governor is set at
maximum performance. This is not optimal to save power but the best
effort until there is a RT patched kernel on Snapdragon.

The previous changes broke sdlog2 on NuttX because no orb_copy was
called after polling in the case when sdlog2 was not actually logging.

Turns out in practice there was not really a difference, so there was
no reason to change it.

This brings better performance, so less missed updates on Snappy, as
well as a bit of a cleanup of the poll and orb_copy logic.

Previously, the MAX and MIN were both 512 meaning that usually it would
start writing at > 512 bytes but only write 512 bytes which results in
a 512 bytes write shortly followed by a e.g. 30 bytes write.

Also, performance (measured in missed poll updates) seems slightly
better on Snapdragon with bigger chunks.

This should lead to less drops on Snapdragon although it's hard to
verify this.

This brings various PRs and fixes.

This only applies parameters from the log file and user-supplied overrides.
It is intended to be called as one of the first startup commands (after
param load), so that during startup, all applications find the parameters
from the replayed system.

Note that this is an optional command and 'replay start' will again load
and apply the parameters in any case.

This adds a new module that does:
- read an parse an ULog file, given via ENV variable 'replay'
- apply all parameters from the log file
- read and apply user-defined override parameters from a file
- publish all messages in 'real-time' from the log file and add a constant
  offset to the timestamp to match the system time.
- apply changed parameters in the log (which are not overridden)

If enabled, orb reads a rules file (./rootfs/orb_publisher.rules) on
startup. This can contain rules about which module is allowed to publish
which topic. It is completely transparent, so a publisher does not know
if he's not allowed to publish, and publications will look as if they
succeeded.

To test, add
#define ORB_USE_PUBLISHER_RULES
to uORBManager.hpp

* updating the camera driver, correct init and keepAlive function

* removing debug output
