The $srctree environment variable gives the path relative to which
'(o)source' statements work (the current directory is used if $srctree
is unset). It is set to $ZEPHYR_BASE in cmake/kconfig.cmake, so there's
no need to qualify the source of Kconfig.zephyr in sample Kconfig files
(or in external projects).
All 'source's in Zephyr assume that the Zephyr root directory is used as
the srctree as well, and would break otherwise.
Remove the $(ZEPHYR_BASE)s to make it clearer that all 'source'
statements work relative to the Zephyr root. There was some user
confusion on IRC.
Also explain how things work in the documentation.

Some terminals literally interprets shell output data. Hence to print
a message in new line shell needs to send `\r\n` each time. To minimize
flash usage user can now send `\n` as a line delimiter and shell will
automatically add missing CR character.

Prepend the text 'cmake_minimum_required(VERSION 3.8.2)' into the
application and test build scripts.
Modern versions of CMake will spam users with a deprecation warning
when the toplevel CMakeLists.txt does not specify a CMake
version. This is documented in bug #8355.
To resolve this we include a cmake_minimum_required() line into the
toplevel build scripts. Additionally, cmake_minimum_required is
invoked from within boilerplate.cmake. The highest version will be
enforced.
This patch allows us to afterwards change CMake policy CMP000 from OLD
to NEW which in turn finally rids us of the verbose warning.
The extra boilerplate is considered more acceptable than the verbosity
of the CMP0000 policy.

On flash NVS was stored one entry after another including the metadata
of each entry. This has the disadvantage that when an incomplete write
is performed (e.g. due to power failure) the complete sector had to be
rewritten to get a completely functional system.
The present rewrite changed the storage in flash of the data. For each
sector the data is now written as follows: the data itself at the
beginning of the sector (one after the other), the metadata (id, length,
data offset in the sector, and a crc of the metadata) is written from
the end of the sector. The metadata is of fixed size (8 byte) and for
a sector that is completely occupied a metadata entry of all zeros is
used.
Writing data to flash always is done by:
1. Writing the data,
2. Writing the metadata.
If an incomplete write is done NVS will ignore this incomplete write.
At the same time the following improvements were done:
1. NVS now support 65536 sectors of each 65536 byte.
2. The sector size no longer requires to be a power of 2 (but it
still needs to be a multiple of the flash erase page size).
3. NVS now also keeps track of the free space available.

The nvs module has some disadvantages for larger block size. The data
header and slot are taking up to much space. A rewrite is proposed that
reduces the used storage space for systems with write block size > 4.
The data storage in flash is now one unit consisting of: data_length,
data_id, data and data_length again in a multiple of the write block
size. The data_length at the end is used to validate the correctness of
the flash write and also allows to travel backwards in the filesystem.
As a comparison, on a system with block size 8 byte, a 32 bit values
now fits 1 block including the metadata (length and id). This used to
be 3 blocks.
The data_length will occupy 1 byte if the data length is less than 128
byte, it will occupy 2 byte if the data length is 128 byte or more. The
data length is limited to 16383 byte.
Each write to flash is verified by a read back of the data.
The read performance is improved because reading is done backwards so
the latest items are found first.
When the filesystem is locked it can be unlocked by calling
reinit(), this will clear flash and setup everything for storage.
