Bruce Richardson 3031749c2d remove trailing whitespaces
This commit removes trailing whitespace from lines in files. Almost all
files are affected, as the BSD license copyright header had trailing
whitespace on 4 lines in it [hence the number of files reporting 8 lines
changed in the diffstat].

[Thomas: remove spaces before tabs in libs]
[Thomas: remove more trailing spaces in non-C files]
