issues with the previous implementation:
- no setting auto completion
- very manual and error prone way of getting/setting variables
- tons of code duplication
- useless instance names for processes, threads
Now settings can easily be defined like option values. The new settings makes use of the "OptionValue" classes so we can re-use the option value code that we use to set settings in command options. No more instances, just "does the right thing".

lldb_private::Error objects the rules are:
- short strings that don't start with a capitol letter unless the name is a
class or anything else that is always capitolized
- no trailing newline character
- should be one line if possible
Implemented a first pass at adding "--gdb-format" support to anything that
accepts format with optional size/count.

OptionGroupFormat. Updated OptionGroupFormat to be able to also use the
"--size" and "--count" options. Commands that use a OptionGroupFormat instance
can choose which of the options they want by initializing OptionGroupFormat
accordingly. Clients can either get only the "--format", "--format" + "--size",
or "--format" + "--size" + "--count". This is in preparation for upcoming
chnages where there are alternate ways (GDB format specification) to set a
format.

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.

the FormatManager class. Modified the format arguments in any commands to be
able to use a single character format, or a full format name, or a partial
format name if no full format names match.
Modified any code that was displaying formats to use the new FormatManager
calls so that our help text and errors never get out of date.
Modified the display of the "type format list" command to be a bit more
human readable by showing the format as a format string rather than the single
character format char.

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.

new OptionGroup subclasses for:
- output file for use with options:
long opts: --outfile <path> --append--output
short opts: -o <path> -A
- format for use with options:
long opts: --format <format>
- variable object display controls for depth, pointer depth, wether to show
types, show summary, show location, flat output, use objc "po" style summary.
Modified ValueObjectMemory to be able to be created either with a TypeSP or
a ClangASTType.
Switched "memory read" over to use OptionGroup subclasses: one for the outfile
options, one for the command specific options, and one for the format.

inline contexts when the deepest most block is not inlined.
Added source path remappings to the lldb_private::Target class that allow it
to remap paths found in debug info so we can find source files that are elsewhere
on the current system.
Fixed disassembly by function name to disassemble inline functions that are
inside other functions much better and to show enough context before the
disassembly output so you can tell where things came from.
Added the ability to get more than one address range from a SymbolContext
class for the case where a block or function has discontiguous address ranges.

set by default when dumping registers. If you want to see all of the register
sets you can use the "--all" option:
(lldb) register read --all
If you want to just see some register sets, you can currently specify them
by index:
(lldb) register read --set 0 --set 2
We need to get shorter register set names soon so we can specify the register
sets by name without having to type too much. I will make this change soon.
You can also have any integer encoded registers resolve the address values
back to any code or data from the object files using the "--lookup" option.
Below is sample output when stopped in the libc function "puts" with some
const strings in registers:
Process 8973 stopped
* thread #1: tid = 0x2c03, 0x00007fff828fa30f libSystem.B.dylib`puts + 1, stop reason = instruction step into
frame #0: 0x00007fff828fa30f libSystem.B.dylib`puts + 1
(lldb) register read --lookup
General Purpose Registers:
rax = 0x0000000100000e98 "----------------------------------------------------------------------"
rbx = 0x0000000000000000

rdx = 0x0000000000000000

gs = 0x0000000000000000
As we can see, we see two constant strings and the PC (register "rip") is
showing the code it resolves to.
I fixed the register "--format" option to work as expected.
Added a setting to disable skipping the function prologue when setting
breakpoints as a target settings variable:
(lldb) settings set target.skip-prologue false
Updated the user settings controller boolean value handler funciton to be able
to take the default value so it can correctly respond to the eVarSetOperationClear
operation.
Did some usability work on the OptionValue classes.
Fixed the "image lookup" command to correctly respond to the "--verbose"
option and display the detailed symbol context information when looking up
line table entries and functions by name. This previously was only working
for address lookups.

so we can instantiate them, and also moved the code that
can get the specific subclass for a OptionValue into the
OptionValue class.

To do this currently, it must be done in multi-line mode:
(lldb) commands regex --help "Help text for command" --syntax "syntax for command" <cmd-name>
Any example that would use "f" for "finish" when there are no arguments,
and "f <num>" to do a "frame select <num>" would be:
(lldb) commands regex f
Enter multiple regular expressions in the form s/find/replace/ then terminate with an empty line:
s/^$/finish/
s/([0-9]+)/frame select %1/
(lldb) f 11
frame select 12
...
(lldb) f
finish
...
Also added the string version of the OptionValue as OptionValueString.
