Greg Clayton 57abc5d6a6 <rdar://problem/13854277>
<rdar://problem/13594769>

Main changes in this patch include:
- cleanup plug-in interface and use ConstStrings for plug-in names
- Modfiied the BSD Archive plug-in to be able to pick out the correct .o file when .a files contain multiple .o files with the same name by using the timestamp
- Modified SymbolFileDWARFDebugMap to properly verify the timestamp on .o files it loads to ensure we don't load updated .o files and cause problems when debugging

The plug-in interface changes:

Modified the lldb_private::PluginInterface class that all plug-ins inherit from:

Changed:

virtual const char * GetPluginName() = 0;

To: 

virtual ConstString GetPluginName() = 0;

Removed:

virtual const char * GetShortPluginName() = 0;

- Fixed up all plug-in to adhere to the new interface and to return lldb_private::ConstString values for the plug-in names. 
- Fixed all plug-ins to return simple names with no prefixes. Some plug-ins had prefixes and most ones didn't, so now they all don't have prefixed names, just simple names like "linux", "gdb-remote", etc.

Platform select documents a -S option but doesn't accept it, now it does.

Fixed an issue where the platform auto select code was changing the architecture and causing the wrong architecture to be assigned to the target.

Daniel Malea 93a64300f8 Fix Linux build warnings due to redefinition of macros:
- add new header lldb-python.h to be included before other system headers
- short term fix (eventually python dependencies must be cleaned up)

Greg Clayton 3bcdfc0ec1 <rdar://problem/12798131>
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

Greg Clayton 1c5f186f30 Added new options to "target create" and "target modules add".
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.

Greg Clayton 4ae4160974 Fixed an issue in the platform options where if no architecture was specified where the platform would fail to select itself with something like:
(lldb) platfrom select remote-ios

Switch over to the "*-apple-macosx" for desktop and "*-apple-ios" for iOS triples.

Also make the selection process for auto selecting platforms based off of an arch much better.

Greg Clayton b3a40ba812 Platforms can now auto-select themselves if you specify a full target triple when doing a "target create" command.
Each platform now knows if it can handle an architecture and a platform can be found using an architecture. Each platform can look at the arch, vendor and OS and know if it should be used or not.

Greg Clayton 86edbf41d1 Cleaned up many error codes. For any who is filling in error strings into
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.

Greg Clayton cac9c5f971 Added to the public API to allow symbolication:
- New SBSection objects that are object file sections which can be accessed
  through the SBModule classes. You can get the number of sections, get a 
  section at index, and find a section by name.
- SBSections can contain subsections (first find "__TEXT" on darwin, then
  us the resulting SBSection to find "__text" sub section).
- Set load addresses for a SBSection in the SBTarget interface
- Set the load addresses of all SBSection in a SBModule in the SBTarget interface
- Add a new module the an existing target in the SBTarget interface
- Get a SBSection from a SBAddress object

This should get us a lot closer to being able to symbolicate using LLDB through
the public API.

Johnny Chen 7c575b3b3a Refactoring: replace a bunch of static array size computation or hardcoded constant
with a template function 'arraysize(static_array)', defined in Utils.h.

Greg Clayton f3dd93c888 Added the notion of an system root for SDKs. This is a directory where all
libraries and headers exist. This can be specified using the platform select
function:

platform select --sysroot /Volumes/remote-root remote-macosx

Each platform subclass is free to interpret the sysroot as needed.

Expose the new SDK root directory through the SBDebugger class. 

Fixed an issue with the GDB remote protocol where unimplemented packets were
not being handled correctly.

Greg Clayton effe5c956b Added new OptionGroup classes for UInt64, UUID, File and Boolean values.
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.

Greg Clayton 7260f6206f Centralized a lot of the status information for processes,
threads, and stack frame down in the lldb_private::Process,
lldb_private::Thread, lldb_private::StackFrameList and the 
lldb_private::StackFrame classes. We had some command line
commands that had duplicate versions of the process status
output ("thread list" and "process status" for example). 

Removed the "file" command and placed it where it should
have been: "target create". Made an alias for "file" to
"target create" so we stay compatible with GDB commands.

We can now have multple usable targets in lldb at the
same time. This is nice for comparing two runs of a program
or debugging more than one binary at the same time. The
new command is "target select <target-idx>" and also to see
a list of the current targets you can use the new "target list"
command. The flow in a debug session can be:

(lldb) target create /path/to/exe/a.out
(lldb) breakpoint set --name main
(lldb) run
... hit breakpoint
(lldb) target create /bin/ls
(lldb) run /tmp
Process 36001 exited with status = 0 (0x00000000) 
(lldb) target list
Current targets:
  target #0: /tmp/args/a.out ( arch=x86_64-apple-darwin, platform=localhost, pid=35999, state=stopped )
* target #1: /bin/ls ( arch=x86_64-apple-darwin, platform=localhost, pid=36001, state=exited )
(lldb) target select 0
Current targets:
* target #0: /tmp/args/a.out ( arch=x86_64-apple-darwin, platform=localhost, pid=35999, state=stopped )
  target #1: /bin/ls ( arch=x86_64-apple-darwin, platform=localhost, pid=36001, state=exited )
(lldb) bt
* thread #1: tid = 0x2d03, 0x0000000100000b9a a.out`main + 42 at main.c:16, stop reason = breakpoint 1.1
  frame #0: 0x0000000100000b9a a.out`main + 42 at main.c:16
  frame #1: 0x0000000100000b64 a.out`start + 52

Above we created a target for "a.out" and ran and hit a
breakpoint at "main". Then we created a new target for /bin/ls
and ran it. Then we listed the targest and selected our original
"a.out" program, so we showed two concurent debug sessions
going on at the same time.
