Name matching was working inconsistently across many places in LLDB. Anyone doing name lookups where you want to look for all types of names should used "eFunctionNameTypeAuto" as the sole name type mask. This will ensure that we get consistent "lookup function by name" results. We had many function calls using as mask like "eFunctionNameTypeBase | eFunctionNameTypeFull | eFunctionNameTypeMethod | eFunctionNameTypeSelector". This was due to the function lookup by name evolving over time, but as it stands today, use eFunctionNameTypeAuto when you want general name lookups. Either ModuleList::FindFunctions() or Module::FindFunctions() will figure out the right kinds of names to lookup and remove the "eFunctionNameTypeAuto" and replace it with the exact subset of what the name can be.
This checkin also changes eFunctionNameTypeAny over to use eFunctionNameTypeAuto to reflect this.

- copy lldb python module into directory specified with CMAKE_INSTALL_PREFIX
- make liblldb.so a symlink (to liblldb.so.X.Y where X.Y is the LLVM version)

-Remove tracing of fork/vfork until we add support for tracing inferiors' children on Linux.
-Add trace exec option for ptrace so that we don't receive legacy SIGTRAP signals on execve calls.
-Add handling of SIGCHLD sent by kernel (for now, deliver the signal to the inferior).

"source list -n <func>" can now show more than one location that matches a function name. It will unique multiple of the same source locations so they don't get displayed. It also handles inline functions correctly.

Show variables that were in the debug info but optimized out. Also display a good error message when one of these variables get used in an expression.

regions that aren't actually allocated in the
process. This cache is used by the expression
parser if the underlying process doesn't support
memory allocation, to avoid needless repeated
searches for unused address ranges.
Also fixed a silly bug in IRMemoryMap where it
would continue searching even after it found a
valid region.

Fixed "target symbols add" to correctly extract all module specifications from a dSYM file that is supplied and match the symbol file to a current target module using the UUID values if they are available.
This fixes the case where you add a dSYM file (like "foo.dSYM") which is for a renamed executable (like "bar"). In our case it was "mach_kernel.dSYM" which didn't match "mach_kernel.sys".

Python breakpoint actions can return False to say that they don't want to stop at the breakpoint to which they are associated
Almost all of the work to support this notion of a breakpoint callback was in place, but two small moving parts were missing:
a) the SWIG wrapper was not checking the return value of the script
b) when passing a Python function by name, the call statement was dropping the return value of the function
This checkin addresses both concerns and makes this work
Care has been taken that you only keep running when an actual value of False has been returned, and that any other value (None included) means Stop!

process StopLocker (if there is a process) before it will hand out SBValues. We were doing this in
an ad hoc fashion previously, and then playing whack-a-mole whenever we found a place where we should
have been doing this but weren't. Really, it doesn't make sense to be poking at SBValues when the target
is running, the dynamic and synthetic values can't really be computed, and the underlying memory may be
incoherent.

Most importantly, have DoReadGPR/DoReadFPU/DoReadEXC return -1
to indicate failure if they're called. Else these could override
the Error setting for the relevant thread state -- if the core file
didn't include a floating point thread state, for instance, these
functions would clear the Error setting for that register set and
lldb would display random bytes as those registers' contents.

Provide a mechanism through which users can disable loading the Python scripts from dSYM files
This relies on a target setting: target.load-script-from-symbol-file which defaults to false ("do NOT load the script")
You need to set it to true before creating your target (or in your lldbinit file if you constantly rely on this feature) to allow the scripts to load
