With srcline key/sort'ing it's useful to have line numbers in the annotate window. This patch implements this. Use objdump -l to request the line numbers and save them in the line structure. Then the browser displays them for source lines. The line numbers are not displayed by default, but can be toggled on with 'k' There is one unfortunate problem with this setup. For lines not containing source and which are outside functions objdump -l reports line numbers off by a few: it always reports the first line number in the next function even for lines that are outside the function. I haven't found a nice way to detect/correct this. Probably objdump has to be fixed. See https://sourceware.org/bugzilla/show_bug.cgi?id=16433 The line numbers are still useful even with these problems, as most are correct and the ones which are not are nearby. v2: Fix help text. Handle (discriminator...) output in objdump. Left align the line numbers.
