Some more were added since the cleanup pass in June 2018. See e.g.
commit 2d50da70a1 ("drivers: ipm: Kconfig: Remove redundant 'default n'
properties") for a motivation. It also avoids people wondering whether
or not they need to put in 'default n'.

When optimizations are disabled more RAM is used and we get a stack
overflow on CONFIG_LOG_PROCESS_THREAD_STACK_SIZE. To rectify this,
increase the stack size when CONFIG_NO_OPTIMIZATIONS.
This does not scale well, and will have to be replaced by a a more
general solution eventually, but in the mean time it follows the
existing best practice established by the GCOV infrastructure in

The new Logger subsys uses a very robust formatter function in minimal
libc: _prf(). This adds up to ~3K flash. For resource constrained
devices running samples that don't use the extra formatting options,
allow them to select LOG_DISABLE_FANCY_OUTPUT_FORMATTING to revert
back to vprintk.
MCUBOOT is one such sample that has a very limited amount of output
and benefits from the flash savings due to small bootloader partition
sizes.

Changed 'in place' mode to bypass logger system and directly
call active backends. With this approach memory footprint of
the logger can be significantly reduced in terms of RAM and ROM.

Refactored blocking operation of RTT backend. Log_output buffer
is used directly in case of blocking operation. Detection of
host presence added. Prevent use of RTT lock when in panic mode.
Removed pending on data being read by the host on every message.
Refactor gives savings of 300 bytes in ROM and 120 bytes in RAM.

Consistently use
config FOO
bool/int/hex/string "Prompt text"
instead of
config FOO
bool/int/hex/string
prompt "Prompt text"
(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).
The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.
Most of the grunt work was done by a modified version of
https://unix.stackexchange.com/questions/26284/how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some
of the rarer variations had to be converted manually.

Thread can be waken up if number of buffered log messages exceeds

Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.
Remove some 'default ""' properties on string symbols too.
Also make definitions more consistent by converting some
config FOO
<type>
prompt "foo"
definitions to a shorter form:
config FOO
<type> "foo"
This shorthand works for int/hex/string symbols too, not just for bool
symbols.

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.
