The death of lib/ftp.c, merged into lib/rpmio.c.

The death of lib/ftp.c, merged into lib/rpmio.c.
Start composting the rpmio API.
Preliminary (not working) support for HTTP PUT.
build.c: Check fd for NULL and use Ferror() for Fopen return.
build/parseSpec.c: ditto
build/pack.c: Use fdGetFP() rather than fpio->ffileno().
build/parseSpec.c: ditto
build/pack.c: Use Stat/Mkdir wrappers.
build/pack.c: Do Fflush before fdDup so that writes can remain buffered.
lib/install.c: ditto
build/parsePrep.c: Skip over URL leadin when writing %prep scriptlet.
lib/misc.c: Rewrite to use simpler urlPath(). Restore checks on local fs.
lib/rpmchecksig.c: Open with "r+" rather than "w" to avoid truncation.
lib/url.c: Do lazy malloc of u->buf in rpmio.c checkResponse().
lib/rpmio.c: Make persist/contentLength per-fd rather than per-url.
lib/rpmio.c: Add wr_chunked method for HTTP PUT (still broken).
lib/rpmio.c: ftpAbort() should use timedRead.
lib/rpmio.c: Add Fflush().
lib/url.c: urlPath() should return something ("/") on url = NULL (paranoia).
lib/url.c: urlSplit() should return something ("/") on url w/o path.
