731415f00d unix: add kernel module load/unload syscalls on Linux 
InitModule loads a kernel module from an ELF image. FinitModule loads a
kernel module from a file descriptor. DeleteModule unloads a kernel
module.

These syscalls require the CAP_SYS_MODULE capability.

See http://man7.org/linux/man-pages/man2/init_module.2.html and
http://man7.org/linux/man-pages/man2/delete_module.2.html for details.

Also drop deprecated syscalls related to kernel modules from the list
of unimplemented syscalls.

Add ErrnoName and SignalName to get errno and signal name strings from
syscall.Errno and syscall.Signal values, respectively.

This repurposes the errors and signals vars (because they are not used
within x/sys/unix currently) and turns them into slices of struct,
containing errno/signal number, name and description. ErrnoName and
SignalName can then be trivially implemented using sort.Search.

Renaming errors to errorList additionaly allows to avoid package aliases
for the errors package.

syscall was added in Linux kernel 4.11.

See https://github.com/tklauser/statx for an example of how this

1f337fdb7f unix: add Major, Minor and Mkdev functions on Solaris 
Add Major, Minor and Mkdev functions for converting device numbers to
their major/minor components and vice versa.

Use the respective functions provided by the Solaris libc instead of
reimplementing them.

Test the conversion function with some well-known static device numbers
for devices which should be present on any Solaris system.

Re-generated files on OpenIndiana Hipster 2017.04 (SunOS 5.11) which
also added some previously missing error constants.
