tracefile.c: Seek fix

Made the tracefile.c seek more robust. Fixes a rare crash where high can be
lower than low in a seek.

Matthew Khouzam <matthew.khouzam@ericsson.com>:
I am including an example to better illustrace my fix.
the current binary search has a case where high can be lower then low.
An example: 51 blocks, the element is somewhere in the 12th block.
trace of before :
 low : 0, high 51 , block_num -1
 low : 0, high 24 , block_num 25
 low : 13, high 24 , block_num 12
 low : 13, high 17 , block_num 18
 low : 13, high 14 , block_num 15
 low : 13, high 12 , block_num 13
This will assert and fail.
The trace after will produce the following walkthrough
 low : 0, high 51 , block_num -1
 low : 0, high 24 , block_num 25
 low : 0, high 24 , block_num 12
 Found!

This avoids duplicating the factor reduction (or "propagation") code in every

every pair of traces and reduction is performed separately from the analysis.

If a trace pair doesn't have factors but the inverse pair does (ie. no factors
to convert the time from trace 1 to 0 but there are factors to convert the
time from trace 0 to 1), the factors from the inverted pair are used (after
