7ace85e636 PLUGINS: Simplify ELF plugin providers & DLObject subclasses 
* Remove DLObject virtual methods allocSegment and freeSegment.
  As long as all DLObject implementations use memalign + free to
  allocate/release segments, there is no point in wrapping those.
  This enables further simplifications.
* Add TemplatedELFPlugin template class. Use this instead of explicit
  ELFPlugin subclasses.
* Rename DLObject::discard_symtab to discardSymtab

99cf0e3936 COMMON: Undo changes to common/ptr.h, remove Common::ScopedPtrC 
The deletePointer() method approach cannot work, as it is called
by the destructor of the base class.
A possible correct solution would be to enhance ScopedPtr with a
"deleter" object like SharedPtr. But this seems overkill as long as we
need it in only one place.

13b904d282 Merge from gsoc2010-plugins 
This merge was extremely difficult to carry out. It wasn't entirely SVN's fault -- there were several merges to the branch that were done by hand. Please check for any issues and regressions. Also note that the DS makefile was not copied over since the "one at a time" plugin mode currently has too much fragmentation ie. it doesn't work.

8df4278ba8 PLUGINS: fixed issue with R_MIPS_32 relocations 
Caused crash in some games. The problem was referring to the right segment. R_MIPS_32 relocations can be found in the Shorts segment, but still need to refer to the main segment if the symbol is found there.

2596143e2b PLUGINS: Additional plugin check for the ELF loader. 
The ELF loader does not have access to the symbols of the main
executable, it just relocates symbols to it via fixed offsets. We need
to make sure that loaded plugins are from the same link process to
prevent crashes. An embedded build date is used for that.

ae408db07f PLUGINS: Use the C++ ABI to call dtors when unloading a plugin. 
Avoid linking all plugins against libstdc++ to free up some memory
(about ~40kb on Wii per plugin). Enable it on GameCube, Wii, DS and PSP
(PS2 doesn't have __cxa_atexit support in its libc).

364acaae45 PLUGINS: Remove spurious extra allocation. 
Elf32_Phdr.p_align is to align the memory location of the loaded
segment, not to extend its size. The size of the scratch area
(like .bss and .sbss) is p_memsz-p_filesz, which has to be set to
zero by the loader.
