glx: load dri driver with RTLD_LOCAL so dlclose never fails to unload

There is no reason anymore to load with RTLD_GLOBAL and for some driver
this even result in dlclose failing to unload leading to catastrophic
failure with swrast fallback.

egl_dri2: fix wayland_platform when drm_platform is not set

The build fails with implicit delaration of drmGetCap (xf86drm.h)
Were we're including the header only when building the DRM_PLATFORM.

Wayland backend can operate without DRM_PLATFORM so replace the
guard, and fold in drmGetCap() usage to silence compiler warnings.

st/egl: do not link against libloader

Move the link to the final targets, like any other place in
mesa/gallium. This allows better visibilty and will prevent
us from including the library archive twice.

loader: allow attempting more than one method of PCI identification.

loader_get_pci_id_for_fd() and loader_get_device_name_for_fd() now attempt
all available strategies to identify the hardware, instead of conditionally
compiling in a single test.  The existing libudev and DRM approaches have
been retained, attempting first libudev (if available) and then DRM (if
necessary).

loader: add optional /sys filesystem method for PCI identification.

Introduce a simple PCI identification method of looking up the answer
the /sys filesystem (available on Linux).  Attempted after libudev, but
before DRM.

Disabled by default (available only when the --enable-sysfs configure
option is specified).
