d5b310f2a3 Avoid going through Platform when creating a NativeProcessProtocol instance
Summary:
This commit avoids the Platform instance when spawning or attaching to a process in lldb-server.
Instead, I have the server call a (static) method of NativeProcessProtocol directly. The reason
for this is that I believe that NativeProcessProtocol should be decoupled from the Platform
(after all, it always knows which platform it is running on, unlike the rest of lldb).
Additionally, the kind of platform actions a NativeProcessProtocol instance is likely to differ
greatly from the platform actions of the lldb client, so I think the separation makes sense.

After this, the only dependency NativeProcessLinux has on PlatformLinux is the ResolveExecutable
method, which needs additional refactoring.

This is a resubmit of r241672, after it was reverted due to build failueres on non-linux
platforms.

c307c27035 Revert r241672, which breaks the OS X build by introducing a dependency on
platform-specific symbols that are not implemented on OS X.

The build error that caused this is

Undefined symbols for architecture x86_64:

d3173f34e8 Refactor many file functions to use FileSpec over strings.
Summary:
This should solve the issue of sending denormalized paths over gdb-remote
if we stick to GetPath(false) in GDBRemoteCommunicationClient, and let the
server handle any denormalization.

GDBRemoteCommunicationServerLLGS and the command interpreter from

3eb4b4589e Remove trap code from disassembly.
Summary:
NativeProcessProtocol uses ReadMemory internally for setting/checking
breakpoints but also for generic memory reads (Handle_m), this change adds a
ReadMemoryWithoutTrap for that purpose. Also fixes a bunch of misuses of addr_t
as size/length.

Test Plan: `disassemble` no longer shows the trap code.

43d79053d7 Fixed remote failures in TestCPP11EnumTypes, probably others
Typically, LLGS only sends stdout/stderr notifications when the inferior
process is running.

Because LLGS reads stdout from the process in a separate thread, sometimes
these stdout notifications can be received after the server has sent a thread
stop message. The host isn't expecting stdout to be generated by the target
after a stop message and these messages interfere with the host's request/
response paradigm.

7cb18bf537 Fetch module specification from remote process also
Previously the remote module sepcification was fetched only from the
remote platform. With this CL if we have a remote process then we ask it
if it have any information from a given module. It is required because
on android the dynamic linker only reports the name of the SO file and
the platform can't always find it without a full path (the process can
do it based on /proc/<pid>/maps).

00bdca6839 Don't close pseudo terminal master file descriptor on EOF
Some application on Linux an all application on android close stdout and
stderr during the libc exit stage. Previously the master file descriptor
of the pseudo terminal used to communicate with the inferior was closed
on an EOF causing a race condition and a possible SIGHUP on process
exit. After this change the master file descriptor will be closed by the
destructor of the GDBRemoteCommunicationServerLLGS class.
