Implement server_address_new()

When creating a local socket/pipe (server_start()) Neovim used vim_tempname() to
generate a unique socket path. For Windows UNIX filepaths cannot be used as
pipe names (they must start with \\.\pipe\). This commit replaces the use of
vim_tempname() for server addresses with server_address_new().

server_address_new() generates unique names for local sockets/pipes - for UNIX
it uses vim_tempname(), for Windows generates names in the form

    \\.\pipe\nvim-PID-COUNTER

where PID is the current process id, and COUNTER is a static uint32_t counter
incremented with every call. This function is now used for server_start() and
server_init() when no address is available.
