fix API : deal with the optional underscore
A field can be prefixed by an underscore internally by the tracer.
This provides the abilility for the user to specify the underscore or
not (depending if he read the metadata or the tracepoint event
definition).
This is a fallback mechanism, so if the request fails, we prefix an
underscore to the field name and request it again.
Also, the bt_ctf_field_name function now removes the optional
underscore.
A quick benchmark shows that calling the bt_ctf_get_field without the
underscore on a field that requires an underscore adds around 151
nanoseconds to the call on a core 2 duo (tested in a loop of
1000000
iterations).

lib: open trace error handling fix
When a trace from a trace collection path fails, consider this as a hard
error. Print errors to stderr rather than stdout.
The end goal is to never show an output if any of the trace specified
(or trace within a trace collection) fails to open.

source which increments once per nanosecond.

Use 64-bit type for packet and content size
Expression filestats.st_size * CHAR_BIT wraps around very easily
when stored to 32-bit size_t. Currently BabelTrace cannot handle
input larger than 256Mb because of this and diagnostic messages
from this function can be incorrect because of overflow.
This patch fixes my immediate problem, but further work is needed
for proper large file support i.e. handling files bigger than 2Gb.

API : iterator get and set position
This patch implements the save and restore position on a iterator.
Passed successfully these tests :
- test 1:
save the position
read n events (tested with multiple values of n)
restore
compare the outputs
- test 2:
in loop until the end of the trace :
save the position
read 5 events
restore the position
read 5 events
compare each block of 5 events
- test 3:
save the position before printing the first event
parse the trace entirely
restore to the beginning
parse the trace entirely
compare the 2 outputs
- test 4:
seek in the future (manually tweaked the values to restore to)
compare with a normal trace starting from the restore point
[ edit: use g_new/g_new0/g_free instead of malloc/calloc/free.
Use g_new0 anytime a structure is not explicitly initialized by
a helper, so if it grows in the future with new fields, they will be
zeroed. ]
