Quite a lot of the code in common/relates to booting and images. Before
adding more it seems like a good time to move the code into its own
directory.
Most files with 'boot' or 'image' in them are moved, except:
- autoboot.c which relates to U-Boot automatically running a script
- bootstage.c which relates to U-Boot timing
Drop the removal of boot* files from the output directory, since this
interfers with the symlinks created by tools and there does not appear
to be any such file from my brief testing.

After successful transfer of whole image only two things can happen:
- BootROM starts execution of data block, which changes UART baudrate
back to 115200 Bd,
- board crashes and causes CPU reset
In both cases UART baudrate is reset to the default speed. So there is
no need to send special magic sequence to inform kwboot that baudrate is
going to be reset and kwboot does not need to wait for this event and
can do it immediately after BootROM acknowledges end of xmodem transfer.
Move ARM code for sending magic sequence from main baudrate change
section to binhdr_pre section which is executed only before changing
baudrate from the default value of 115200 Bd to some new value. Remove
kwboot code waiting for magic sequence after successful xmodem transfer.
Rationale: sometimes when using very high UART speeds, magic sequence is
damaged and kwboot fails at this last stage. Removal of this magic
sequence makes booting more stable.
Data transfer protocol (xmodem) is using checksums and retransmit, so it
already deals with possible errors on transfer line.

The ARM code we inject into the image to change baudrate back to the
default value of 115200 Baud, which is run after successful UART transfer
of the whole image, cannot use stack as at this stage stack pointer is not
initialized yet.
Stack can only be used when BootROM is executing binary header, to
preserve state of registers, since BootROM expects that.
Change the ARM baudrate code to not use stack at all and put binary
header specific pre + post code (which stores and restores registers) into
separate arrays.
The baudrate change code now jumps at it's end and expects that there is
either code which returns to the BootROM or jumps to the original exec

Kwboot puts each xmodem packet to kernel queue, then waits until all bytes
of that packet are transmitted over UART and then waits for xmodem reply
until it is received into kernel queue.
If some reply is received during the time we are waiting until all bytes
are transmitted, then kernel puts them into the queue and returns it to
kwboot in next read() call.
So there is no need to wait (with tcdrain() function) until all bytes from
xmodem packet are transmitted over UART, since any reply received either
during that time or after is returned to kwboot with the next read().
Therefore do not call tcdrain() after each xmodem packet sent. Instead
directly wait for any reply after putting xmodem packet into write kernel
queue.
This change could speed up xmodem transfer in case tcdrain() function waits
for a longer time.

Currently when kwboot receive some garbage reply which does not understand,
it waits 1s before it tries to resend packet again.
The most common error on UART is that receiver sees some bit flipped which
results in invalid reply.
This behavior slows down xmodem transfer over UART as basically on every
error kwboot is waiting one second.
To fix this, try to resend xmodem packet for first 3 attempts immediately
without any delay. If broken reply is received also after the 3 attempts,
continue retrying with 1s delay like it was before.
