Konstantin Belousov 6297a3d843 Create shared (readonly) page. Each ABI may specify the use of page by ... setting SV_SHP flag and providing pointer to the vm object and mapping address. Provide simple allocator to carve space in the page, tailored to put the code with alignment restrictions. Enable shared page use for amd64, both native and 32bit FreeBSD binaries. Page is private mapped at the top of the user address space, moving a start of the stack one page down. Move signal trampoline code from the top of the stack to the shared page.
