Optionally run a vendor-specific b2g.sh "init" file

[joneschrisg]

Here's my use case: I need to some framebuffer device hackery, because life sucks sometimes. The only sane place I could think to include that was b2g.sh. However, no way that's something we want to take upstream, it's very specific to Raspberry Pi.

I landed a hack to just import b2g.sh into my device/.../ dir, but that sucks. But deadline approacheth.

My thought was to add a vendor hook to b2g.sh to support that use case. Something along the lines of

test -x /system/bin/b2g_vendor_init.sh && /system/bin/b2g_vendor_init.sh

near the beginning of /system/bin/b2g.sh. Can anyone think of better ways?

I can make this change (eventually), but if it's just going to get r-, no point wasting anyone's time.
