[RFH/Patch 1/2] http.c: style cleanups

[Junio C Hamano]

The file is littered with coding style violations; this cleans-up before I
touch it with the next patch.

 - We do not initialize statics to NULL/0; we let BSS take care of it
   instead.

 - Asterisk that means a pointerness comes next to variable, not type;
   i.e. a decl looks like "type *variable", not "type* variable".

 - A single-statement in true/false clause of an "if () ... else ...;"
   statement comes on its own line, without curlies {} around it.

Signed-off-by: Junio C Hamano <gitster@pobox.com>

 * This is not what I am asking for help by sending the series, but the
   next one is.
