Fix: lazy-mmap() streams when flushing
This fixes an issue when empty streams are created as the stream
creation will mmap() the file in preparation for the first event.
This results in "empty" stream files ending up with a non-zero size
which is invalid since no packet headers are found by the reader.
This change ensures that stream files are only mmap'ed on the first
stream flush and that empty streams are stored as size-0 files.

Fix: lock stream class after assigning stream id
Fixes a bug that was introduced by
2f100782 which made it possible
to set custom stream class IDs.
The stream class is frozen when a stream of its type is instanciated.
However, the trace or writer must still assign a unique ID to the stream
class if none were set prior. This modification moves the stream class
locking (freeze) after the ID assignment check.

Add utility function to validate CTF identifiers
Introduces bt_ctf_validate_identifier() which validates a given
identifier against the list of CTF reserved keywords.
This function may evolve to perform additional validity checks in

Fix: allow empty CTF files
There are expected situtations in which CTF producers (like LTTng) can
generate empty CTF trace files. The current babeltrace behavior is to
trigger an error when an empty file is encountered. Change this to allow
reading the rest of the trace anyway.
