Commit 37f815cad0 ("moveconfig: Use a function to read files") adds a
helper function that can read a file as lines, but strips the newline
characters. This change broke parts of moveconfig code that relied on
their existence, resulting in a few issues:
Configs that are defined as empty aren't removed from header files (e.g.
"#define CONFIG_REMAKE_ELF"). Make regex patterns use '\b' to match word
boundaries instead of '\W' (which matched the newlines) so these lines
still match and get removed.
All changes in defconfig are considered removed by savedefconfig even
if they weren't, and line continuations in the headers aren't recognized
and removed properly, because their checks explicitly look for a newline
character. Remove the character from both comparisons.
The printed diff of header files is wrongly formatted and raises an
IndexError if a blank line was removed. Let print() print the new lines,
and use size-independent ways to check strings to fix the diff output.

At present there is quite a bit of ad-hoc code reading from files. The
most common case is to read the file as lines. Put it in a function and
set the unicode encoding correctly.
Avoid writing back to a file when there are obviously no changes as this
speeds things up slightly.

With the move to using Python 3 for real, we encounter two different
issues. First, the file include/video_font_data.h includes at least one
UTF-16 character. Given that it does not include any CONFIG symbols it
is easiest to just ignore this file. Next, we encounter similar
problems with some dts/dtsi files that come from Linux. In this case
it's easiest to simply ignore all dts/dtsi files as there will not be
CONFIG symbols for us to migrate in them.

A large number of changes have happened upstream since our last sync
which was to 375506d. The reason to do the upgrade at this point is for
improved Python 3 support.
As part of this upgrade we need to update moveconfig.py and
genboardscfg.py the current API. This is:
- Change "kconfiglib.Config" calls to "kconfiglib.Kconfig"
- Change get_symbol() calls to syms.get().
- Change get_value() to str_value.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

Corresponds to 375506d (File writing nit) from upstream
(https://github.com/ulfalizer/Kconfiglib).
Adds proper 'imply' support and fixes a few minor issues, one of which
previously triggered the following weird warning:
configs/taurus_defconfig: /tmp/tmpisI45S:6: warning: assignment to SPL_LDSCRIPT changes mode of containing choice from "arch/$(ARCH)/cpu/u-boot-spl.lds" to "y"
The change in 8639f69 (genconfig.py: Print defconfig next to warnings)
was reapplied.
tools/moveconfig.py previously depended on a hack that merged 'select's
with 'imply's. It was modified to look at the union of
Symbol.get_selected_symbols() and Symbol.get_implied_symbols(), which
should give the same behavior.
tools/genboardscfg.py was verified to produce identical board.cfg's
before and after the change.

Adjust moveconfig to make use to buildman's toolchains. This should make

One missing feature is the ability to specify the toolchain on the command
line with a special environment variable, e.g. CROSS_COMPILE_ARM. I'm not
sure if that is useful, but if it is it could be implemented in buildman.

It is useful to be able to process only a subset of boards to save time.
Often that subset is defined by the defconfig files in a git commit. This
change allows things like:
# Build the database
./tools.moveconfig.py -b
# Find some implying configs
./tools/moveconfig.py -i CONFIG_X
# Add some 'imply' statements to Kconfig files
./tools/moveconfig.py -i CONFIG_X -a CONFIG_A,CONFIG_B
# Reprocess the defconfig files to see if we can drop some changes
git show --stat | ./tools/moveconfig.py -s -d -
# Update the commit, with fewer defconfig changes
gii commit -au
Where the commit contains defconfig files, this will reprocess them to
take account of the imply statements that you added.

Some CONFIG options can be implied by others and this can help to reduce
the size of the defconfig files. For example, CONFIG_X86 implies
CONFIG_CMD_IRQ, so we can put 'imply CMD_IRQ' under 'config X86' and
all x86 boards will have that option, avoiding adding CONFIG_CMD_IRQ to
each of the x86 defconfig files.
Add a -i option which searches for such options.
