d2d1: Use D2D1_ALPHA_MODE_IGNORE if D2D1_ALPHA_MODE_UNKNOWN is used for creating hwnd render targets. Also, alpha mode should not be overwritten with D2D1_ALPHA_MODE_IGNORE just because DXGI_FORMAT_UNKNOWN is specified.

This avoids relying on libunwind, which isn't always available, and which can be brittle (e.g. current git master of libunwind fails, see https://github.com/libunwind/libunwind/pull/203#issuecomment-984126066). This allows unwinding with the EXIDX/EXTBL info which is used normally for C++ exception handling/unwinding. This avoids needing to keep the .so files unstripped and avoids needing libunwind to load .debug_frame from disk instead of the already mapped EXIDX/EXTBL. This patch uses the dl_iterate_phdr function for finding the EXIDX section; keeping this call within #ifdef linux to avoid breaking someone's build, even though it probably is available on most unix (or ELF) platforms. Alternatively, we could add configure checks for this function. This passes all my unwinding tests, for full ELF builds of Wine, built with both GCC and Clang. (It also works for PE builds, where only very few ELF bits need to be unwound.) Signed-off-by: Martin Storsjö <martin@martin.st>

On most ELF platforms on ARM, ARM EHABI is the unwind info format normally used, instead of DWARF like on most other platforms. Currently, when unwinding through ELF objects with libunwind, the libraries don't have any .eh_frame section mapped at runtime (since DWARF isn't used for unwinding). Instead, what happens is that libunwind ends up loading .debug_frame from the libraries on disk instead. Therefore, currently, ELF unwinding relies on the .so files not being stripped. This patch adds the necessary EHABI unwinding instructions in the assembly functions that currently have DWARF CFI instructions. EHABI isn't signaled via any specific preprocessor macro, but is signaled by the absence of other unwind mechanisms (such as __ARM_DWARF_EH__ and __SEH__, or maybe SjLj). Mark the asm functions in the preloaders as .cantunwind, to avoid undefined references to __aeabi_unwind_cpp_pr* functions. Also mark other assembly functions as .cantunwind; for signal_exit_thread this is essential if the function is marked with .fnstart/.fnend - otherwise exiting threads does hang. (pthread_exit internally calls _Unwind_ForcedUnwind, which would hang if signal_exit_thread had .fnstart without any matching unwind info). This would, in principle, allow unwinding through these functions with libunwind, for versions of libunwind that can parse the EHABI unwind info - see e.g. https://github.com/libunwind/libunwind/commit/4d779f55c0d0a3814453517e54cd0f7bed69ca74. (This commit isn't yet in any current release AFAIK). Unwinding with EHABI via libunwind would require a few tweaks to the libunwind interface usage in unix/signal_arm.c though, since e.g. the unw_get_proc_info call fails if there's no .eh_frame or .debug_frame available.

It returns a static buffer pointer and will free the first returned pointer on the second call.

This change is adding DWARF (CFI) unwind information to the hand-written assembly of the `__wine_syscall_dispatcher` function. This enables unwinding through the dispatcher from the Linux stack into (and through) the Windows stack. The general idea is that the `syscall_frame` struct contains the content of the callee-save registers before the function call (in particular the stack pointer and the return address). At any point of the execution, we have a pointer into the `syscall_frame` in $ebx, $ecx, $ebp, or $esp. For the CFI codes the general idea is that we are defining the computations of the callee-save registers based on the `syscall_frame` using DWARF’s `breg` instruction, rather than relative to CFA.
