x86/asm/entry: Move the 'thunk' functions to arch/x86/entry/ These are all calling x86 entry code functions, so move them close to other entry code. Change lib-y to obj-y: there's no real difference between the two as we don't really drop any of them during the linking stage, and obj-y is the more common approach for core kernel object code.

x86, um: Use the same style generated syscall tables as native Now when the native kernel uses a single style of generated system call table, follow suite for UML and implement the same style, all in C. This requires __NR_syscall_max and NR_syscalls to be generated; on native this is done in asm-headers.h but that file is common to all UML architectures; therefore put it in user-headers.h instead which already have accommodations for architecture-specific values.
