PDB is Microsoft's debug information format, and although we cannot yet generate it, we still must be able to consume it. Reason for this is that debug information for system libraries (e.g. kernel32, C Runtime Library, etc) only have debug info in PDB format, so in order to be able to support debugging of system code, we must support it. Currently this code should compile on every platform, but on non-Windows platforms the PDB plugin will return 0 capabilities, meaning that for now PDB is only supported on Windows. This may change in the future, but the API is designed in such a way that this will require few (if any) changes on the LLDB side. In the future we can just flip a switch and everything will work. This patch only adds support for line tables. It does not return information about functions, types, global variables, or anything else. This functionality will be added in a followup patch.
