Zachary Turner a746e8e58a Start converting usages of off_t to other types.
off_t is a type which is used for file offsets.  Even more
specifically, it is only used by a limited number of C APIs that
deal with files.  Any usage of off_t where the variable is not
intended to be used with one of these APIs is a bug, by definition.

This patch corrects some easy mis-uses of off_t, generally by
converting them to lldb::offset_t, but sometimes by using other
types such as size_t, when appropriate.

The use of off_t to represent these offsets has worked fine in
practice on linux-y platforms, since we used _FILE_OFFSET_64 to
guarantee that off_t was a uint64.  On Windows, however,
_FILE_OFFSET_64 is unrecognized, and off_t will always be 32-bit.
So the usage of off_t on Windows actually leads to legitimate bugs.

Saleem Abdulrasool 3985c8c646 sanitise sign comparisons
This is a mechanical change addressing the various sign comparison warnings that
are identified by both clang and gcc.  This helps cleanup some of the warning
spew that occurs during builds.

lldb remembers not-found source file, setting target.source-map doesn't make it re-check for it. Now this is fixed. Each time the source path remappings get updated, the modification ID in the PathMappingList gets bumped and then we know the re-check for sources.

Sean Callanan f601503ae6 Fixed a bug in the path remapper that caused
a crash if the path to be remaped was NULL.

Greg Clayton 67cc06366c Reimplemented the code that backed the "settings" in lldb. There were many 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".

Fixed a case where the source path remappings on the module were too expensive to
use when we try to verify (stat the file system) that the remapped path points to
a valid file. Now we will use the lldb_private::Module path remappings (if any) when
parsing the debug info without verifying that the paths exist so we don't slow down
line table parsing speeds.

There were two problems associated with this radar:
1. "settings show target.source-map" failed to show the source-map after, for example,
   "settings set target.source-map /Volumes/data/lldb/svn/trunk/test/source-manager /Volumes/data/lldb/svn/trunk/test/source-manager/hidden"
   has been executed to set the source-map.
2. "list -n main" failed to display the source of the main() function after we properly set the source-map.

The first was fixed by adding the missing functionality to TargetInstanceSettings::GetInstanceSettingsValue (Target.cpp)
and updating the support files PathMappingList.h/.cpp; the second by modifying SourceManager.cpp to fix several places
with incorrect logic.

Also added a test case test_move_and_then_display_source() to TestSourceManager.py, which moves main.c to hidden/main.c,
sets target.source-map to perform the directory mapping, and then verifies that "list -n main" can still show the main()
function.

Greg Clayton 7e14f91dbd Fixed the SymbolContext::DumpStopContext() to correctly indent and dump
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.
