XML-RPC client: Transport.request() retries on EPIPE error

The EPIPE error occurs when the server closes the socket and the client sends a
"big" XML-RPC request (I don't know exactly the size threshold).

request() just have to ignore the error because single_request() closes the
socket on error, and so the next call to single_request() will open a new
socket.

Remove also a comment in the HTTP client because it's now wrong: see r70643 and
issue #5542.

Remove special logic that closes HTTPConnection socket on EPIPE.

If the socket is closed, the client has no chance to read the response
from the server.  EPIPE means that it isn't possible to write more
data from the socket, but not that it is impossible to read.

  Ensure that sys.prefix can reliably be found
  on OSX. This fixes a small issue that was exposed
  by running test_subprocess through regrtest (and
  hence in a subdirectory).

  Without this patch running python.exe from the
  build tree will fail when these tree conditions
  are true:
  1) the CWD is not the root of build tree
  2) python.exe is found through $PATH
  3) the framework is not yet installed

signed/unsigned chars or on integers directly derived from those. In all
cases, it could be replaced by a simple cast to (unsigned char). Reasons
for the change:

  a) Make the comment more explicit.

  b) If char is unsigned, the cast is optimized away.

  c) If char is unsigned, gcc emits spurious "array subscript
     has type 'char'" warnings.
