Jason Molenda ede3193bbd Add a "force_kill" arg to Process::Destroy(). This is needed after
the changes in r233255/r233258.  Normally if lldb attaches to
a running process, when we call Process::Destroy, we want to detach
from the process.  If lldb launched the process itself, ::Destroy
should kill it.

However, if we attach to a process and the driver calls SBProcess::Kill()
(which calls Destroy), we need to kill it even if we didn't launch it
originally.

The force_kill param allows for the SBProcess::Kill method to force the
behavior of Destroy.

Zachary Turner 93749ab3cf Further reduce the header footprint of Process.h
No functional change here, only deletes unnecessary headers
and moves one function's body from the .h file to the .cpp.

Ilia K cc39d3f4bd Fix Arg0 argument after r229110. The problem was that Arg0ValueChangedCallback isn't twitching when Arg0 was updated, therefore target was launched with empty 1st argument or without it at all. In this patch I update Arg0 by hand.

Ilia K 8f37ca56d6 Add -exec-arguments command
Summary:
This patch adds -exec-arguments command for lldb-mi. -exec-arguments command allows to specify arguments for executable file in MI mode. Also it contains tests for that command.

Btw, new added files was formatted by clang-format.

and also to break a dependency cascade that caused functions linking

Stephane Sezer f2ef94e770 Make the platform process connect path less chatty.
Summary:
If a stream contains an empty string, no need to append it to the output
(otherwise we end up with a blank line). Also, no need to print a status
message when the state changes to connected, as this string brings no
information -- "Process 0" does not mean anything to the user, and the
process being connected has no meaning either.

Test Plan:
Connect to a remote linux platform mode daemon with `platform select
remote-linux` followed by `platform connect ...`, create a target and
run it, observe the output. Also, run the full test suite (dosep.py).

Before:
    (lldb) [...] connect, etc.
    (lldb) r
    Process 0 connected

    Process 5635 launched: '/Users/sas/Source/test' (x86_64)
    Process 5635 stopped

After:
    (lldb) [...] connect, etc.
    (lldb) r
    Process 5635 launched: '/Users/sas/Source/test' (x86_64)
    Process 5635 stopped

Greg Clayton 8012cadbf3 Fixed more fallout from running the test suite remotely on iOS devices.
Fixed include:
- Change Platform::ResolveExecutable(...) to take a ModuleSpec instead of a FileSpec + ArchSpec to help resolve executables correctly when we have just a path + UUID (no arch).
- Add the ability to set the listener in SBLaunchInfo and SBAttachInfo in case you don't want to use the debugger as the default listener. 
- Modified all places that use the SBLaunchInfo/SBAttachInfo and the internal ProcessLaunchInfo/ProcessAttachInfo to not take a listener as a parameter since it is in the launch/attach info now
- Load a module's sections by default when removing a module from a target. Since we create JIT modules for expressions and helper functions, we could end up with stale data in the section load list if a module was removed from the target as the section load list would still have entries for the unloaded module. Target now has the following functions to help unload all sections a single or multiple modules:

    size_t
    Target::UnloadModuleSections (const ModuleList &module_list);

    size_t
    Target::UnloadModuleSections (const lldb::ModuleSP &module_sp);

Greg Clayton dc6224e0a3 Make the "synchronous" mode actually work without race conditions.
There were many issues with synchronous mode that we discovered when started to try and add a "batch" mode. There was a race condition where the event handling thread might consume events when in sync mode and other times the Process::WaitForProcessToStop() would consume them. This also led to places where the Process IO handler might or might not get popped when it needed to be.

Todd Fiala 5163792b7b Adjust process launch --disable-aslr to take true/false value.
This change modifies the 'process launch' --disable-aslr option to take a boolean argument.  If the user directly specifies --disable-aslr {true,false}, that setting will control whether the process is launched with ASLR disabled accordingly.  In the event that the setting is not explicitly made on the process launch command line, then the value is retrieved from the target.disable-aslr setting (i.e. settings show target.disable-aslr).

This reverses out the options validators changes.  We'll get these

Restores broken tests on FreeBSD, Linux, MacOSX.

Zachary Turner de963e9a09 Adds the notion of an OptionValidator.
The purpose of the OptionValidator is to determine, based on some
arbitrary set of conditions, whether or not a command option is
valid for a given debugger state.  An example of this might be
to selectively disable or enable certain command options that
don't apply to a particular platform.

This patch contains no functional change, and does not actually
make use of an OptionValidator for any purpose yet.  A follow-up
patch will begin to add the logic and users of OptionValidator.

Greg Clayton 44d937820b Merging the iohandler branch back into main.
The many many benefits include:
1 - Input/Output/Error streams are now handled as real streams not a push style input
2 - auto completion in python embedded interpreter
3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use
4 - it is now possible to use curses to drive LLDB (please try the "gui" command)

We will need to deal with and fix any buildbot failures and tests and arise now that input/output and error are correctly hooked up in all cases.

Greg Clayton b09c5384b0 Centralized the launching of a process into Target::Launch()
While investigating test suite failures when running the test suite remotely, I noticed we had 3 copies of code that launched a process:
1 - in "process launch" command 
2 - SBTarget::Launch() with args
3 - SBTarget::Launch() with SBLaunchInfo

"process launch" was launching through the platform if it was supported (this is needed for remote debugging) and the 2 and 3 were not.

Now all code is in one place.
