Lay down the foundation for this refactor work so that nsReflowStatus could
be converted to bit-fields piece by piece, and each patch can be built (but
may not pass tests).
This change causes some build warnings, due to some debug logs printing
nsReflowStatus as an integer, but that will be fixed by Part 24 later.
All the operators related to uint32_t will be removed at the end of this
patch series by Part 23.
The yoda conditions are swapped in order to build successfully.
DisplayReflowExit() incorrectly declares aStatus as uint32_t. Change it to
const reference because nsReflowStatus is now a class.

Delete the "or 0 for no movement in that direction" from the CanAdjustEdges
document in nsMenuPopupFrame.h because the only caller in nsResizerFrame.cpp
never passes 0 to it.

I think there are three advantages of this change:
1. removes some dependencies from layout / painting code to pre-computed
value stuff in the style system;
2. makes it easier to audit usage of specific fields in style structs
(which is probably a side effect of the first one);
3. potentially improves performance since it doesn't go through the
unnecessary general logic in ExtractComputedValue.
Also, combined with the part before, we get a unified list for visited-
dependent properties so that we can ensure the assertion here and the
style difference calc code are consistent.

In GetFlowArea(), "Shrink our band's height if needed." computation was
moved to the end because we need to pass the unmodified |blockEnd| to
compute LineRight() and LineLeft().
Revamp OutsetBorderRadii() to allow negative margin to reduce the radius,
but not below zero. Also implement the cubic formula required by the spec.
https://drafts.csswg.org/css-shapes/#valdef-shape-box-margin-box
OutsetBorderRadii() is now tailored only for margin-box with border-radius,
so it might no longer be suitable for other scenarios.

After using enum class, a switch-case warning in CombineBreakType is caught.
This is one of such kind safty checks that we would like to gain.
Fix it by adding default case for switch-case in CombineBreakType.

The main renaming was generated with the following python script:
```
import sys
import re
CAMEL_CASE_REGEX = re.compile(r"(^|_|-)([A-Z])([A-Z]+)")
DISPLAY_REGEX = re.compile(r"\bNS_STYLE_DISPLAY_([^M][A-Z_]+)\b")
def to_camel_case(ident):
return re.sub(CAMEL_CASE_REGEX,
lambda m: m.group(2) + m.group(3).lower(), ident)
def constant_to_enum(constant):
return "StyleDisplay::" + to_camel_case(constant) + ("_" if constant == "NONE" else "")
def process_line(line):
return re.sub(DISPLAY_REGEX,
lambda m: constant_to_enum(m.group(1)), line)
lines = []
with open(sys.argv[1], "r") as f:
for line in f:
lines.append(process_line(line))
with open(sys.argv[1], "w") as f:
for line in lines:
f.write(line)
```
And the following shell commands:
```
find . -name '*.cpp' -exec python display.py {} \;
find . -name '*.h' -exec python display.py {} \;

Drop the aPresContext and aBlockFrame params from RenumberListsInBlock
and rename it RenumberChildFrames. Use 'this' instead of aBlockFrame.
Rename RenumberListsFor to RenumberFrameAndDescendants.
This patch is generated by the following commands (note: if you're running
using OS X's sed, which accepts slightly different flags, you'll have to
specify an actual backup suffix in -i, or use gsed from Homebrew):
hg stat -c \
| cut -c 3- \
| tr '\n' '\0' \
| xargs -0 -P 8 gsed --follow-symlinks 's/\bnsCSSProperty\b/nsCSSPropertyID/g' -i''
Then:
hg mv layout/style/nsCSSProperty.h layout/style/nsCSSPropertyID.h
... and finally, manually renaming nsCSSProperty in the include guard in
nsCSSProperty.h.

The modification to nsAbsoluteContainingBlock.h and nsBlockFrame.cpp are
needed to fix the build error due to the file order changed in the unified
build.
The #includes are fixed by the following script:
function rename() {
find .\
-type f\
! -path "./obj*"\
! -path "./.git"\
! -path "./.hg"\
\( -name "*.cpp" -or\
-name "*.h" \)\
-exec sed -i -e "s/$1/$2/g" "{}" \;
}
rename "nsHTMLReflowMetrics\.h" "mozilla\/ReflowOutput\.h"
