Enrico Granata 6d37cc6501 This checkin removes the last Cocoa formatters that were implemented in Python and reimplements them in C++. The Python Cocoa formatters are not shipped as part of LLDB anymore, but still exist in the source repository for user reference. Python formatters still exist for STL classes and users can still define their own Python formatters

Enrico Granata e1fb1654c8 Quick fix for the libc++ std::map synthetic children provider
If you try to access any child > 0 without having touched child 0, LLDB won't be able to reconstruct type information from the debug info.
Previously, we would fail.
Now, we simply go fetch child 0 and then come back.

Enrico Granata b5d9d630d8 Greg created a new API on SBProcess to get an ID that is guaranteed to be unique even in situations where underlying platforms would actually duplicate or hardcode PIDs
The Python data formatters use a per-process cache that was previously keying off the PID. Moving that to be based on this new notion of unique ID.

Enrico Granata d50f18b1a0 Part 1 of a series of fixes meant to improve reliability and increase ease of bug fixing for data formatter issues.
We are introducing a new Logger class on the Python side. This has the same purpose, but is unrelated, to the C++ logging facility
The Pythonic logging can be enabled by using the following scripting commands:
(lldb) script Logger._lldb_formatters_debug_level = {0,1,2,...}
0 = no logging
1 = do log
2 = flush after logging each line - slower but safer
3 or more = each time a Logger is constructed, log the function that has created it
more log levels may be added, each one being more log-active than the previous
by default, the log output will come out on your screen, to direct it to a file:
(lldb) script Logger._lldb_formatters_debug_filename = 'filename'
that will make the output go to the file - set to None to disable the file output and get screen logging back
Logging has been enabled for the C++ STL formatters and for Cocoa class NSData - more logging will follow


synthetic children providers for classes list and map (both libstdcpp and libcxx) now have internal capping for safety reasons
this will fix crashers where a malformed list or map would not ever meet our termination conditions

to set the cap to a different value:

(lldb) script {gnu_libstdcpp|libcxx}.{map|list}_capping_size = new_cap (by default, it is 255)

you can optionally disable the loop detection algorithm for lists

(lldb) script {gnu_libstdcpp|libcxx}.list_uses_loop_detector = False

Enrico Granata 8c69c96dc9 Changed several of the Cocoa formatters to match the output style that Xcode uses internally to provide summaries
This has been done for those summaries where the difference is only cosmetic (e.g. naming things as items instead of values, ...)
The LLDB output style has been preserved when it provides more information (e.g. telling the type as well as the value of an NSNumber)

Test cases have been updated to reflect the updated output style where necessary

Enrico Granata cfdafa37b4 Several performance-oriented changes to the introspecting data formatters:
(a) the SystemParameters object is now passed around to the formatters; doing so enables the formatters to reuse computed values for things such as pointer-size and endianness
     instead of repeatedly computing these on their own
 (b) replacing the global ISA cache with a per-process one
 (c) providing a per-process types cache where each formatter can store the types it needs to operate, and be sure to find them the next time without recalculating them
     this also enables formatters to share types if they agree on a local naming convention
 (d) lazy fetching of data from Objective-C runtime data structures
     data is fetched as needed and we stop reading as soon as we determine that an ISA is actually garbage
