Some reorganization that results from a new method I'm moving to to
maintaining this opensource tree. Some of this reorganization is
entirely a result of reorganization: blank lines in a few different
places, etc. Here are the others:
1) I've added a new file, util.h, with lots of new, helpful routines,
most notably StringPrintf (printf returning a string). I've also
moved some routines from the .cc and unittest.cc file here, such as
the CHECK macros, testing framework, and #ifdefs for 16-bit ints.
Quite a bit of code was rewritten to use these new routines.
2) I noticed that the special-case setenv() code was only needed for
windows systems, so I moved it to port.h/cc.
3) I also had to add a new vsnprintf wrapper in port.h/cc, to support
StringPrintf.
4) A few places I used an old name, commandlineflags, instead of
gflags. Most or all of these should be fixed now.
5) Some of my copyright dates weren't quite right. Fixed them up.
6) In some .cc files, I added using directives to not have to use
std:: so much.
7) I've added a minor new test, adding 10000 or so flags to see how
the system scales.
8) Some compile-warning fixes, such as int -> size_t when appropriate,
and better protected #defines in mutex.h
9) The .h files gained some logic defining GFLAGS_DLL_DECL. This is
true even for .h files outside the windows directory, which will never
have these dll issues. But one big advantage of my new organization
is auto-generating the windows versions of these files from the unix
versions, so there's some unnecessary (but harmless) duplication as a
result.
10) Fixed a bug in rpm.sh which would cause an unnecessary crash when
dpkg was missing.
