This patch fixes two corner-cases of finding RTT control block.
The first one is when there was a partial match (even single byte) at
the end of loaded buffer (uint8_t buf[1024]), but this was not part of
full match. In that case `cb_offset` was not updated correctly and the
returned `*address` was lower by the legth of the partial match. In case
of searched 'SEGGER RTT' (the default control block ID) string, it was
enough to match `buf[1023] == 'S'`, which is quite likely to happen, and
the `*address` was offset by 1 (e.g. it was 0x20000fff instead of
0x20010000).
Updating (or even maintaining) `cb_offset` is not needed, as start
address of control block can be calculated based on memory address that
was loaded into `uint8_t buf[1024]`, the offset within this buffer and
the length of expected string.
The second issue is when control block is prepended with a byte that
matches first ID character, e.g. there is `SEGGER RTT` control block ID
is prepended by another `S`, making memory contents be `SSEGGER RTT`. In
that case there was no match found.
Fix that issue by making sure that tested byte is always compared with
first byte of expected control block ID.
While at it, change names of local variables to better describe their
meaning.

With the old checkpatch we cannot use the correct format for the
SPDX tags in the file .c, in fact the C99 comments are not allowed
and we had to use the block comment.
With the new checkpatch, let's switch to the correct SPDX format.
Change created automatically through the command:
sed -i \
's,^/\* *\(SPDX-License-Identifier: .*[^ ]\) *\*/$,// \1,' \
$(find src/ contrib/ -name \*.c)

Replace the FSF boilerplate with the SPDX tag.
The SPDX tag on files *.c is incorrect, as it should use the C99
single line comment using '//'. But current checkpatch doesn't
allow C99 comments, so keep using standard C comments, by now.

Including config.h as first is required for every C file.
Add it to the C files that still miss it.

Real Time Transfer (RTT) is an interface specified by SEGGER based on
basic memory reads and writes to transfer data bidirectionally between
target and host.
Every target that supports so called "background memory access", which
means that the target memory can be accessed by the debugger while the
target is running, can be used.
RTT is especially of interest for targets which do not support Serial
Wire Output (SWO) (e.g. ARM Cortex-M0) or where using semihosting is
not possible (e.g. real-time applications) [1].
The data transfer is organized in channels where each channel consists
of an up- and/or down-channel. See [2] for more details.
Channels are exposed via TCP connections. One or more RTT server can be
assigned to each channel to make them accessible to an unlimited number
of TCP connections.
The current implementation does not respect buffer flags which are used
to determine what happens when writing to a full buffer.
Note that the implementation is designed in a way that the RTT
operations can be directly performed by an adapter (e.g. J-Link).
