GNU Time updates (slightly off-topic)

[Assaf Gordon]

Hello,

It's time to update GNU time...

As the first step,
I've converted the code to use modern gnulib structure
and added the standard testing framework.
Secondly, I've fixed few issues based on downstream Debian patches.
There shouldn't be any functional changes in the current code.
Later I hope to add few more features.

As the changes are substentials, I haven't pushed to the 'master'
branch yet.

If anyone is interested, the updates are available here:
 https://git.savannah.gnu.org/cgit/time.git/log/?h=modernize1

Or locally with:

 git clone -b modernize1 git://git.sv.gnu.org/time.git
 cd time
 ./bootstrap
 ./configure
 make
 make check

Comments and suggestions are very welcomed.
