Bug 1259889 Part 2 [1] cannot be reverted cleanly, so I manually undo those
changes in this patch. That is, remove the ability for html.css to
invalidate dynamically since it was added specifically for details element.
Although reftest-stylo.list explicit mentions "DO NOT EDIT!", but I still
remove details pref from the file, since it doesn't harm to edit it anyway.

This patch also:
* Removes some now-unnecessary code from nsFlexContainerFrame, which was for jumping from wrapped-placeholders to their out-of-flow frames (for DOM comparisons). This code is now unnecessary because placeholders won't be wrapped anymore.
* Updates some reftests with abspos content to match the updated spec's expectations, with one marked as "fails" for the time being (until bug 1269046 implements css box alignment, which we need to render that test correctly).

The major change to the Iterator is due to the fact that the end of a
LinkedList is represented by nullptr.
Also delete the type conversion functions which are no longer needed.

Change the logic that moves the main summary to the front from operating
on generated frames in DetailsFrame::SetInitialChildList() to operating
on frame construction item list in AddFrameConstructionItemsInternal()
so that it will be correct when cooperating with ::first-line.
The root cause of the bug reported is because when specifying
::first-line on details element, the first frame of summary element,
which is generated due to ib-split, will be wrapped in nsFirstLineFrame.
The original code fails to find the summary frame in the wrapper frame
and triggers assertion because of the second ib-split summary frame. To
fix that, we need to descend into the child list of wrapper frames when
checking the main summary.
Add original test case as a crashtest as well as reftests to clearly
reproduce the issue.
Note that in the reftest, the blue color in ::first-line is applied
incorrectly to the second line in the summary due to bug 520605.

SummaryFrame had been removed in bug 1258657, so now HTMLSummaryElement
is always rendered as an ordinary inline or block frame. Therefore, the
check in FindHTMLData is not needed anymore.

Per bug 1299753 comment 20, SetFlags() is designed for flag propagation
to continuations during block reflow. To avoid misuse, I expand
SetFlags() directly in the only reasonable caller nsBlackFrame::Init(),
and replace other usages by AddStateBits().

nsCSSFrameConstructor::ConstructNonScrollableBlock() has logic to
determine whether to create a block formatting context for a block
frame. I refactor the function to make it reusable by
nsCSSFrameConstructor::ConstructDetailsFrame().
Also, make NS_NewBlockFrame() accept two arguments as other frame
factory functions so that it could be pointed by BlockFrameCreationFunc.
NS_NewBlockFormattingContext is changed accordingly.
The construction for a scrollable DetailsFrame will be further revised
in Part 3.

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 {} \;
```

This includes, for example :hover.
Also removes the call to IsStyledByServo() in the document constructor, it's not
only unnecessary, but also we call UpdateStyleBackendType() too early.
