The getopt library has a structure called option (lowercase). We
have a structure called Option (uppercase). previously the two
structures had exactly the same definitions, and we were doing a
C-style cast of an Option* to an option*. C-style casts don't
bother to warn you when you cast to unrelated types, but in the
original OptionValidator patch I modified the definition of Option.
This patch fixes the errors by building an array of option
structures and filling it out the correct way before passing it to
the getopt library.
This also fixes one other source of test failures: an uninitialized
read that occurs due to not initializing a field of the
OptionDefinition.

Cleaned up the option parsing code to always pass around the short options as integers. Previously we cast this down to "char" and lost some information. I recently added an assert that would detect duplicate short character options which was firing during the test suite.
This fix does the following:
- make sure all short options are treated as "int"
- make sure that short options can be non-printable values when a short option is not required or when an option group is mixed into many commands and a short option is not desired
- fix the help printing to "do the right thing" in all cases. Previously if there were duplicate short character options, it would just not emit help for the duplicates
- fix option parsing when there are duplicates to parse options correctly. Previously the option parsing, when done for an OptionGroup, would just start parsing options incorrectly by omitting table entries and it would end up setting the wrong option value

For "target create" you can now specify "--no-dependents" to not track down and add all dependent shared libraries. This can be handy when doing manual symbolication. Also added the "--symfile" or "-s" for short so you can specify a module and a stand alone debug info file:
(lldb) target create --symfile /tmp/a.dSYM /usr/bin/a
Added the "--symfile" option to the "target modules add" for the same reason. These all help with manualy symbolication and expose functionality that was previously only available through the public API layer.

variables prior to running your binary. Zero filled sections now get
section data correctly filled with zeroes when Target::ReadMemory
reads from the object file section data.
Added new option groups and option values for file lists. I still need
to hook up all of the options to "target variable" to allow more complete
introspection by file and shlib.
Added the ability for ValueObjectVariable objects to be created with
only the target as the execution context. This allows them to be read
from the object files through Target::ReadMemory(...).
Added a "virtual Module * GetModule()" function to the ValueObject
class. By default it will look to the parent variable object and
return its module. The module is needed when we have global variables
that have file addresses (virtual addresses that are specific to
module object files) and in turn allows global variables to be displayed
prior to running.
Removed all of the unused proxy object support that bit rotted in
lldb_private::Value.
Replaced a lot of places that used "FileSpec::Compare (lhs, rhs) == 0" code
with the more efficient "FileSpec::Equal (lhs, rhs)".
Improved logging in GDB remote plug-in.

Removed the "image" command and moved it to "target modules". Added an alias
for "image" to "target modules".
Added some new target commands to be able to add and load modules to a target:
(lldb) target modules add <path>
(lldb) target modules load [--file <path>] [--slide <offset>] [<sect-name> <sect-load-addr> ...]
So you can load individual sections without running a target:
(lldb) target modules load --file /usr/lib/libSystem.B.dylib __TEXT 0x7fccc80000 __DATA 0x1234000000
Or you can rigidly slide an entire shared library:
(lldb) target modules load --file /usr/lib/libSystem.B.dylib --slid 0x7fccc80000
This should improve bare board debugging when symbol files need to be slid around manually.
