Ilia K 69b95f49f1 Fix handling of double quotes (MI)
Summary:
* Clean CMICmdArgValString::Validate: now it's based on CMIUtilString::SplitConsiderQuotes method:
A bit of introduction:
# Command line is wrapped into CMICmdArgContext.
# CMICmdArgSet is a set of arguments to be parsed. This class contains CMICmdArgContext as a private member.
# MI command is class which is inhereted from CMICmdBase. It contains CMICmdArgSet as a private member.

When command is executed CMICmdBase::ParseArgs() is called. This method adds args for parsing using CMICmdArgSet::Add(). Then CMICmdBase::ParseValidateCmdOptions() is called, which calls CMICmdArgSet::Validate(). Then it gets a number of arguments (using SplitConsiderQuotes().array_length) and for each arguments registered in ParseArgs() tries to validate it using CMICmdArgValBase::Validate(). Every user commands parses this string again (first time it was made in SplitConsiderQuotes) and in case of CMICmdArgValString it was made incorrectly. It searches the first and last quotes (but it should be first and next after first). Besides, it was splitted into 4 cases. 
I'm just using SplitConsiderQuotes directly, and I don't split them by hand again. 

Actually, I think we should do so in every CMICmdArgVal_XXX::Validate() method.

* Enable MiInterpreterExecTestCase.test_lldbmi_target_create test
* Fix MiExecTestCase.test_lldbmi_exec_arguments_set test

All tests pass on OS X.

Ilia K da86749a92 Fix process's output to stdout/stderr (MI)
Summary:
* Add CMIUtilString::Escape/Unescape methods (MI)
* Fix process's output to stdout/stderr (MI):
lldb-mi escapes process's output to show it in the following format:
```
~"..."
```

But previously not all characters were escaped by CMICmnLLDBDebuggerHandleEvents::ConvertPrintfCtrlCodeToString and output of
```
printf("'\n` - it's \\n\x12\"\\\"")
```
looked like:
```
~"'\r\n` - it's \n"\""
```

This patch fixes it by using CMIUtilString::Escape method and now it looks like:
```
~"'\r\n` - it's \\n\x12\"\\\""
```

Greg Clayton bc63aaccf7 Optimize finding the Complete Definition of an ObjC class for debug with .o files with lots of .o files.
When we have a debug map we have an executable with a bunch of STAB symbols and each source file has a N_SO symbol which scopes a bunch of symbols inside of it. We can use this to our advantage here when looking for the complete definition of an objective C class by looking for a symbol whose name matches the class name and whose type is eSymbolTypeObjCClass. If we find one, that symbol will be contained within a N_SO symbol. This symbol gets turned into a symbol whose type is eSymbolTypeSourceFile and that symbol will contain the eSymbolTypeObjCClass which helps us to locate the correct .o file and allows us to only look in that file.

To further accelerate things, if we are looking for the implementation, we can avoid looking at all .o files if we don't find a matching symbol because we have a debug map, which means the objective C symbol for the class can't have been stripped, so we can safely not search all remaining .o files. This will save us lots of time when trying to look for "NSObject" and any other AppKit and Foundation classes that we never have implementation definitions for.

Greg Clayton 1e28adfe75 MacOSX symbol table change to combine the N_GSYM debug map entry with the "_OBJC_CLASS_$_", "_OBJC_METACLASS_$_", and "_OBJC_IVAR_$_" non debug symbols. This allows the symbol that represents the object file to contain the eSymbolTypeObjCClass and eSymbolTypeObjCMetaClass and will help us to be able to efficiently lookup the real definition of an objective C class without loading all .o files linearly to find the .o file that contains the true definition.

Pavel Labath 7257d28025 Skip symlinks to the original file when searching for debug info
Summary:
Symbols::LocateExecutableSymbolFile tries to locate the file in containing the debug info in a
splitdebug configuration. It tries to skip over the original file in its search path, but it was
easily fooled by symlinks. This changes the function to use llvm::sys::fs::equivalent, which can
correctly compare symlinks.

As a side effect, I had to fix one test because the address for the "abort" function resolves on
my system to "__GI_abort" now. With the debug info, the libc on my system contains two symbols
associated with the address of the abort function, and lldb prefers __GI_abort, possibly because
the debug info is associated with it. It would be nice at some point to have it prefer the public
symbol name.

Zachary Turner f4f8740eb0 [CMake] Change lldbAPI to be a CMake OBJECT library.
An OBJECT library is a special type of CMake library that produces
no archive, has no link interface, and no link inputs.  It is like
a regular archive, just without the physical output.  To link
against an OBJECT library, you reference it in the *source* file
list of a library using the special syntax $<TARGET_OBJECTS:lldbAPI>.
This will cause every object file to be passed to the linker
independently, as opposed to a single archive being passed to the
linker.

This is *extremely* important on Windows.  lldbAPI exports all of the
SB classes using __declspec(dllexport).  Unfortunately for technical
reasons it is not possible (well, extremely difficult) to get the
linker to propagate a __declspec(dllexport) attribute from a symbol
in an object file in an archive to a DLL that links against that
archive.  The solution to this is for the DLL to link the object files
directly.  So lldbAPI must be an OBJECT library.

This fixes an issue that has been present since the duplicated
lldbAPI file lists were removed, which would cause linker failures.

As a side effect, this also makes LLDB_DISABLE_PYTHON=1 work again
on Windows, which was previously totally broken.

Greg Clayton 736888c84b Avoid crashing by not mmap'ing files on network mounted file systems.
This is implemented by making a new FileSystem function:

bool
FileSystem::IsLocal(const FileSpec &spec)

Then using this in a new function:

DataBufferSP
FileSpec::MemoryMapFileContentsIfLocal(off_t file_offset, size_t file_size) const;

This function only mmaps data if the file is a local file since that means we can reliably page in data. We were experiencing crashes where people would use debug info files on network mounted file systems and that mount would go away and cause the next access to a page that wasn't paged in to crash LLDB. 

We now avoid this by just copying the data into a heap buffer and keeping a permanent copy to avoid the crash. Updated all previous users of FileSpec::MemoryMapFileContentsIfLocal() in ObjectFile subclasses over to use the new FileSpec::MemoryMapFileContentsIfLocal() function.
