tracepoint: Refactor representation of nested types

Refactor enumeration, sequence, array, structure, and variant types.

Implement internal data structures to support nested types.

All probe providers using ctf_enum(), ctf_array*() and ctf_sequence*()
are switched to this new internal type representation.

Each of sequence, array, struct and variant gain a "alignment" property,
which is a feature which was needed in lttng-modules to express
alignment for an array or sequence of bits.

syscalls: Make the cmd field of fcntl an enum

The fcntl system call has a cmd parameter which is one of multiple
values defined in the linux/fcntl.h file. This field is now an
enumeration of the various possible values.

Here's an example babeltrace output of the fcntl system call:

[...] syscall_entry_fcntl: { cpu_id = 3 }, { fd = 35,
cmd = ( "F_GETFL" : container = 3 ), arg = 140388746332169 }
