EOL 80 limit and supply more alternatives in warning messages.

2.x signed value.  Also, don't waste space on a table full of unsigned longs
when all it needs are unsigned ints (incase anyone builds this without zlib on
a 64-bit unix for some strange reason).

tested by forcing it to compile this version on both 32-bit and 64-bit linux.

 * disable gc during the test run because we are spawning objects and there
   was an exception when calling Popen.__del__
 * Always set an alarm handler so the process doesn't exit if the test fails
   (should probably add assertions on the value of hndl_called in more places)
 * Using a negative time causes Linux to treat it as zero, so disable that test.

Don't let file removal cause the test to fail.

test coverage of valid inputs to zlib.crc32.

All buildbots compile with UCS2...

to reduce our code size (1k data table and tiny bit of code).  It falls back
to its own without zlib.

read 32bit values as unsigned to start with rather than applying signedness
fixups allover the place afterwards.

This hopefully fixes the test_tarfile failure on the alpha/tru64 buildbot.

platforms with a 64-bit long.

The Alpha/Tru64 test problem is a problem in either tarfile or test_tarfile,
not zlib.

crc32 and adler32 return 32-bit values.  by using a long thats larger than
32-bits in these functions they were prevented from wrapping around to their
signed 32-bit value that we want them to return in python 2.x.

Clean-up floating point issues by adding true division and float constants.

Corrected the raw-unicode-escape codec to use UTF-16 surrogates in
this case, just like the unicode-escape codec.

array subscripts.  Using chars are dangerous b/c they are signed
on some platforms and unsigned on others.

From a clean build importing future_builtins would fail since itertools
wasn't built yet.

which made the return value signed.  On the Alpha that also lost data
since sizeof(int) != sizeof(long) and apparently adler32/crc32 return
64 bits of data.  This change keeps the signedness and continues to store the
data in a long rather than an int as was the case before r61449.

  timeout (10.0025) is more than 2 seconds more than expected (0.001)

I'm assuming this problem is caused by DNS lookup.  This change
does a DNS lookup of the hostname before trying to connect, so the time
is not included.
