Summary:
A *.cpp file header in LLDB (and in LLDB) should like this:
```
//===-- TestUtilities.cpp -------------------------------------------------===//
```
However in LLDB most of our source files have arbitrary changes to this format and
these changes are spreading through LLDB as folks usually just use the existing
source files as templates for their new files (most notably the unnecessary
editor language indicator `-*- C++ -*-` is spreading and in every review
someone is pointing out that this is wrong, resulting in people pointing out that this
is done in the same way in other files).
This patch removes most of these inconsistencies including the editor language indicators,
all the different missing/additional '-' characters, files that center the file name, missing
trailing `===//` (mostly caused by clang-format breaking the line).

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
Instead of a function taking an enum value determining which path to
return, we now have a suite of functions, each returning a single path
kind. This makes it easy to move the python-path function into a
specific plugin in a follow-up commit.
All the users of GetLLDBPath were converted to call specific functions
instead. Most of them were hard-coding the enum value anyway, so this
conversion was simple. The only exception was SBHostOS, which I've
changed to use a switch on the incoming enum value.

This is intended as a clean up after the big clang-format commit
(r280751), which unfortunately resulted in many of the comment
paragraphs in LLDB being very hard to read.
FYI, the script I used was:
import textwrap
import commands
import os
import sys
import re
tmp = "%s.tmp"%sys.argv[1]
out = open(tmp, "w+")
with open(sys.argv[1], "r") as f:
header = ""
text = ""
comment = re.compile(r'^( *//) ([^ ].*)$')
special = re.compile(r'^((([A-Z]+[: ])|([0-9]+ )).*)|(.*;)$')
for line in f:
match = comment.match(line)
if match and not special.match(match.group(2)):
# skip intentionally short comments.
if not text and len(match.group(2)) < 40:
out.write(line)
continue
if text:
text += " " + match.group(2)
else:
header = match.group(1)
text = match.group(2)

This renames the LLDB error class to Status, as discussed
on the lldb-dev mailing list.
A change of this magnitude cannot easily be done without
find and replace, but that has potential to catch unwanted
occurrences of common strings such as "Error". Every effort
was made to find all the obvious things such as the word "Error"
appearing in a string, etc, but it's possible there are still
some lingering occurences left around. Hopefully nothing too
serious.

This is forcing to use Error::success(), which is in a wide majority
of cases a lot more readable.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

I have observed an increased flakyness in the buildbots. I suspect something was relying on the
fact that Pipe::Write had an implicit timeout of 1s, which this commit has removed. Reverting
while I investigate.
llvm-svn: 242767
Summary:
This commit adds a WriteWithTimeout method to time Pipe class, analogous to the existing
ReadWithTimeout(). It also changes the meaning of passing zero as a timeout value. Previously,
zero was used as an infinite timeout value. Now, the meaning of zero timeout to return the data
avaiable without sleeping (basically, a non-blocking operation). This makes the behaviour of Pipe
consistent with the Communication/Connection classes. For blocking operatios with infinite
timeout, I introduce a special constant for this purpose.

This patch makes a number of improvements to the Pipe interface.
1) An interface (PipeBase) is provided which exposes pure virtual
methods for any implementation of Pipe to override. While not
strictly necessary, this helps catch errors where the interfaces
are out of sync.
2) All methods return lldb_private::Error instead of returning bool
or void. This allows richer error information to be propagated
up to LLDB.
3) A new ReadWithTimeout() method is exposed in the base class and
implemented on Windows.
4) Support for both named and anonymous pipes is exposed through the
base interface and implemented on Windows. For creating a new
pipe, both named and anonymous pipes are supported, and for
opening an existing pipe, only named pipes are supported.
New methods described in points #3 and #4 are stubbed out on posix,
but fully implemented on Windows. These should be implemented by
someone on the linux / mac / bsd side.

Python one-line execution was using ConnectionFileDescriptor to do
a non-blocking read against a pipe. This won't work on Windows,
as CFD is implemented using select(), and select() only works with
sockets on Windows.
The solution is to use ConnectionGenericFile on Windows, which uses
the native API to do overlapped I/O on the pipe. This in turn
requires re-implementing Host::Pipe on Windows using native OS
handles instead of the more portable _pipe CRT api.
