Krzysztof Chruściński 5a1313f804 drivers: console: rtt: RTT session awareness
In order to avoid bytes dropping when RTT output buffer is full,
RTT session detection algorithm is introduced to the RTT console.
If host session is detected console retries after wait state
expecting host to empty the buffer. If host session is not detected
console drops the byte without retrying.

David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag
Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Jira: ZEP-1457

Carles Cufi 0e650d4eaf drivers: rtt: Lock interrupts around RTT Write
Since RTTWriteNoLock is not thread-safe or preemptable, it is necessary
to lock interrupts around the calls to it.

Carles Cufi 5f1c6ee2c8 console: Add a Segger RTT console driver
The Real Time Terminal functionality of the Segger J-Link
debug probe and software suite allows applications to write
to a certain RAM area that is read in real-time by the
debugger. This is specially useful when a UART is not
available to provide a console.
This commit adds a console driver that outputs over an RTT
"connection".
