[PATCH] quote.h: simplify the inclusion

From: Jonathan Nieder <jrnieder@gmail.com>

Message-ID: <20110105003634.GA5128@burratino>

Attempting to include quote.h without first including strbuf.h results in warnings:

 ./quote.h:33:33: warning: ‘struct strbuf’ declared inside parameter list
 ./quote.h:33:33: warning: its scope is only this definition or declaration, which is probably not what you want
 ./quote.h:34:34: warning: ‘struct strbuf’ declared inside parameter list
 ...

Add a toplevel declaration for struct strbuf to avoid this.

While at it, stop including system headers from quote.h. git source files already need to include git-compat-util.h sooner to ensure the appropriate feature test macros are defined.

Noticed while trying to use quote.h in a source file without strbufs.
