Pavel Labath 3dfb949861 [lldb] Check for and use ptsname_r if available
ptsname is not thread-safe. ptsname_r is available on most (but not all)
systems -- use it preferentially.

In the patch I also improve the thread-safety of the ptsname fallback
path by wrapping it in a mutex. This should guarantee the safety of a
typical ptsname implementation using a single static buffer, as long as
all callers go through this function.

I also remove the error arguments, as the only way this function can
fail is if the "primary" fd is not valid. This is a programmer error as
this requirement is documented, and all callers ensure that is the case.

Jonas Devlieghere 3011d55f72 [lldb/Host] Use cmakedefine01 for LLDB_ENABLE_POSIX
Rename LLDB_DISABLE_POSIX to LLDB_ENABLE_POSIX and use cmakedefine01 for
consistency.

Jonas Devlieghere 61a2bdadb3 [lldb/Host] Use cmakedefine01 for LLDB_ENABLE_TERMIOS
This renames LLDB_CONFIG_TERMIOS_SUPPORTED to LLDB_ENABLE_TERMIOS. It
now also uses cmakedefine01 to keep things consistent with out other
optional dependencies. But more importantly it won't silently fail when
you forget to include Config.h.

Summary:
After rL368069 I noticed that HAVE_SYS_TYPES_H is not defined in
Platform.h, or anywhere else in lldb. This change fixes that.

Pavel Labath 5d4d168c3c [cmake] Move LLDB_DISABLE_LIBEDIT handling code into a central place
This was previously scattered between the main CMakeLists.txt file and
LLDBGenerateConfig.cmake and LLDBConfig.cmake. This caused the some of
the code to be executed in incorrect order. Specifically, the check for
el_winsertstr was done before libedit_LIBRARIES was computed, and so it
always failed on the first run.

Moving it the two checks to a central place makes sure this doesn't
happen again and improves the overall readability.

Pavel Labath 3351381165 [cmake] Detect presence of wide-char libedit at build time
Summary:
Instead of hardcoding a list of platforms where libedit is known to have
wide char support we detect this in cmake. The main motivation for this
is attempting to improve compatibility with different versions of
libedit, as the interface of non-wide-char functions varies slightly
between versions.

Alex Langford 05c10d0def Check for process_vm_readv using CheckSymbolExists
Instead of checking if code compiles, I think it is a better to check
if the symbol exists. This is simpler and should do the same thing.

Chris Bieneman 2246972ecc [CMake] Abstract Config.h generation for Xcode
This patch abstracts the generation of Config.h and creates a dummy project entry point to allow generation of LLDB's Config header without performing a full CMake configuration.

This will enable the Xcode project to generate LLDB's Config header.
