Fix: Field types native byte order refers to the trace
Following a misunderstanding of the CTF specification, the native
byte order was implemented as meaning the host's endianness. It should
refer to the Trace's endianness.
This modification ensures that stream classes, event classes and field
types correctly inherit the trace's endianness when "native" is used.

Fix: lazy-mmap() streams when flushing
This fixes an issue when empty streams are created as the stream

This results in "empty" stream files ending up with a non-zero size

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.

Fix: offset_s and CTF clocks with frequency != 1GHz
Take into account offset_s from the clock description when calculating
the tc_offset in ctf_get_real_timestamp().
Do not assume that the single_clock->offset field is at a frequency of
1GHz. Take into account the its clock frequency.

Fix: Don't assume that PROT_WRITE grants read permissions
The prot flag passed to mmap() is set to PROT_WRITE when the O_RDWR
access flags is used. This assumes that PROT_WRITE grants read
permissions on the mmap'ed region. While this is true on x86, this
causes a segmentation fault on SPARC and, presumably, other
architectures implementing strict access permissions.
CTF Writer needs read permissions since the unaligned integer writes
may use load instructions as the value is read back to perform the
required shifting/masking is performed in the _bt_bitfield_write_*
macros.

Fix Python: Add a comment warning about an API limitation
Add a comment warning about a possible misuse of the events()
API. The objects returned by this function shall not be copied
as they become invalid as soon as the next event is accessed.
It is also invalid to access an event after its generator has

Fix: mmap trace read the stream_id from the first packet
We were hardcoding the stream_id as 0 for mmap traces, causing a

A fix enters in lttng-tools v2.4.2 to send the CTF stream id in the beacon

streams (LTTng channels).
