Pavel Labath d2c4c9b132 [LLGS] Avoid misrepresenting log lines as inferior output
Summary:
in case we are logging to stdout, any log lines from the forked child can be misconstrued to be
inferior output. To avoid this, we disable all logging immediately after forking.

I also fix the implementatoion of DisableAllLogChannels, which was a no-op before this commit.

Zachary Turner a49c59145b Enable thread-safe logging.
Thread-safe logging had been disabled because of a deadlock,
possibly due to a lock acquired during a signal handler.

This patch turns thread safe logging back on and also greatly
reduces the scope of the lock, confining it only to the code that
affects the underlying output stream, instead of all the code that
builds up the formatted log message.  this should resolve the
issue surrounding the deadlock.

Zachary Turner c1592658d5 Introduce a NullLog class, which ignores all messages.
The purpose of this class is so that GetLogIfAllCategoriesSet
can always return an instance of some class, whether it be a real
logging class or a "null" class, which ignores messages.  Code
that is littered with if statements that only log if the pointer
is non-null can get very unwieldy very quickly, so this should
help code readability in such circumstances.

Since I'm in this code anyway, I'm also deleting the
PrintfWithFlags methods, as well as all the flags, since they
appear to be dead code that have been superceded by newer
mechanisms and all the flags are simply ignored.

Zachary Turner 5023257f23 Move some functions from source/lldb.cpp to Utility.
Specifically, there were some functions for converting enums
to strings and a function for matching a string using a specific
matching algorithm.  This moves those functions to more appropriate
headers in lldb/Utility and updates references to include the
new headers.

Zachary Turner a893d3014b Remove Host::Backtrace in favor of llvm::sys::PrintStackTrace()
This removes Host::Backtrace from the codebase, and changes all
call sites to use llvm::sys::PrintStackTrace().  This makes the
functionality available for all platforms, and even for platforms
which currently had a supported implementation of Host::Backtrace,
this patch should enable richer information in stack traces, such
as file and line number information, as well as giving it the
ability to unwind through inlined functions.

Zachary Turner 39de311071 Create a HostThread abstraction.
This patch moves creates a thread abstraction that represents a
thread running inside the LLDB process.  This is a replacement for
otherwise using lldb::thread_t, and provides a platform agnostic
interface to managing these threads.

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.

LLDB is crashing when logging is enabled from lldb-perf-clang. This has to do with the global destructor chain as the process and its threads are being torn down.

All logging channels now make one and only one instance that is kept in a global pointer which is never freed. This guarantees that logging can correctly continue as the process tears itself down.

Greg Clayton 8571963a7c Fixed a case where the result of std::string's c_str() method was being called on a local variable and returned as a const char * incorrectly. We used to cache the thread names for threads in the current host process, but we shoudn't be caching that as the names can change over time, so now a std::string is returned from Host::GetThreadName().

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
