second underscore is a reserved word according with C99.

Flavio Ceolin da49f2e440 coccicnelle: Ignore return of memset
The return of memset is never checked. This patch explicitly ignore
the return to avoid MISRA-C violations.

The only directory excluded directory was ext/* since it contains
only imported code.

Ulf Magnusson 8cf8db3a73 Kconfig: Use a short, consistent style for prompts
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.

Flavio Ceolin d775c2f504 drivers: crypto: Fix input len size for cbc decryption
do_cbc_decrypt() was not accounting IV's size in the input buffer.

Note that tinycrypt expects that IV and cipher text to be contiguous,
but input length must consider only the cipher text.

Ulf Magnusson a816d105a9 drivers: crypto: Kconfig: Remove redundant 'default n' properties
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, and is
inconsistent.

This will make the auto-generated Kconfig documentation have "No
defaults. Implicitly defaults to n." as well, which is clearer than
'default n if ...'

Ulf Magnusson aa26289458 kconfig: Get rid of leading/trailing whitespace in prompts
Leading/trailing whitespace in prompts requires ugly workarounds in
genrest.py, as e.g. *prompt * is invalid RST. strip() all prompts in
Kconfiglib and get rid of the genrest.py workarounds. Add a warning too.

The Kconfiglib update has some unrelated cleanups and fixes (that won't
affect Zephyr).

Ulf Magnusson 93689bdc80 kconfig: Remove no-op selects of choice symbols
Selecting a choice symbol is always a no-op, and the latest version of
Kconfiglib prints a warning. This commit removes all selects of choice
symbols, which might make the Kconfig files a bit clearer and gets rid
of the warnings.

This is just a dumb removal. I did not try to guess the intent of each
select.

Fixes #6849

Kumar Gala 0bfd810d13 i2c: deprecate use of union dev_config
There are several issues with the dev_config union used as a
convenience when calling the i2c_configure api.  One, the union is well
name spaced protected and doesn't convey use with just i2c.  Second
there are assumptions of how the bits might get packed by the union
which can't be guaranteed.  Since the API takes a u32_t lets change in
tree uses to using the macros to setup a u32_t and make the union as
deprecated.
