Zachary Turner 270e99ab0a Fix some posix assumptions related to running shell commands.
This is a resubmit of r223548, which was reverted due to breaking
tests on Linux and Mac.

This resubmit fixes the reason for the revert by adding back some
accidentally removed code which appends -c to the command line
when running /bin/sh.

This resubmit also differs from the original patch in that it sets
the architecture on the ProcessLaunchInfo.  A follow-up patch will
refactor this to separate the logic for different platforms.

Jim Ingham 893c932acf This is the first step of making lldb able to create target-specific things
(e.g. breakpoints, stop-hooks) before we have any targets - for instance in 
your ~/.lldbinit file.  These will then get copied over to any new targets 
that get created.  So far, you can only make stop-hooks.

Breakpoints will have to learn to move themselves from target to target for
us to get them from no-target to new-target.

We should also make a command & SB API way to prime this ur-target.

Zachary Turner d553d00c79 Disable Editline on Windows.
Editline does not work correctly on Windows.  This goes back at
least to r208369, and as a result r210105 was submitted to disable
libedit at runtime on Windows.

More recently, r222163 was submitted which re-writes editline
entirely, but makes the situation even worse on Windows, to the
point that it doesn't even compile.  While it would be easy to
fix the compilation failure, this patch simply stops compiling
Editline entirely on Windows, as the simple compilation fix would
still result in a broken use of select on Windows, and as such a
broken implementation of Editline.

Since Editline was already disabled to begin with on Windows, we
don't attempt to fix the compilation failure or the underlying
issues, and instead just disable it "even more".

Kate Stone e30f11d9ee Complete rewrite of interactive editing support for single- and multi-line input.
Improvements include:
* Use of libedit's wide character support, which is imperfect but a distinct improvement over ASCII-only
* Fallback for ASCII editing path
* Support for a "faint" prompt clearly distinguished from input
* Breaking lines and insert new lines in the middle of a batch by simply pressing return
* Joining lines with forward and backward character deletion
* Detection of paste to suppress automatic formatting and statement completion tests
* Correctly reformatting when lines grow or shrink to occupy different numbers of rows
* Saving multi-line history, and correctly preserving the "tip" of history during editing
* Displaying visible ^C and ^D indications when interrupting input or sending EOF
* Fledgling VI support for multi-line editing
* General correctness and reliability improvements

Jim Ingham 96a1596a7a For some reason, sometimes the directory paths that clang emits have internal
relative paths, like:

/whatever/llvm/lib/Sema/../../include/llvm/Sema/

That causes problems with our type uniquing, since we use the declaration file
and line as one component of the uniquing, and different ways of getting to the
same file will have different directory spellings, though they are functionally
equivalent.  We end up with two copies of the exact same type because of this, 
and that makes the expression parser give "duplicate type" errors.

I added a method to resolve paths with ../ in them and used that in the FileSpec::Equals,
for comparing Declarations and for doing Breakpoint compares as well, since they also
suffer from this if you specify breakpoints by full path (since nobody knows what
../'s to insert...)

Zachary Turner 172d37d3b9 Create a process launcher abstraction.
This implements Host::LaunchProcess for windows, and in doing so
does some minor refactor to move towards a more modular process
launching design.

The original motivation for this is that launching processes on
windows needs some very windows specific code, which would live
most appropriately in source/Host/windows somewhere.  However,
there is already some common code that all platforms use when
launching a process before delegating to the platform specific
stuff, which lives in source/Host/common/Host.cpp which would
be nice to reuse without duplicating.

This commonality has been abstracted into MonitoringProcessLauncher,
a class which abstracts out the notion of launching a process using
an arbitrary algorithm, and then monitoring it for state changes.

The windows specific launching code lives in ProcessLauncherWindows,
and the posix specific launching code lives in ProcessLauncherPosix.
When launching a process MonitoringProcessLauncher is created, and
then an appropriate delegate launcher is created and given to the
MonitoringProcessLauncher.

Zachary Turner b2df30d652 Fix deadlock in Python one-line execution.
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.

* replaces the Process UnixSignals storage with a shared pointer.
* adds a Process constructor variant that can be passed the UnixSignalsSP. When the constructor without the UnixSignalsSP is specified, the Host's default UnixSignals is used.
* adds a host-specific version of GetUnixSignals() that is used when we need the host's appropriate UnixSignals variant.
* replaces GetUnixSignals() overrides in PlatformElfCore, ProcessGDBRemote, ProcessFreeBSD and ProcessLinux with code that appropriately sets the Process::UnixSignals for the process.
