/*
* These all return:
* 0 for complete success
* -1 for a miscellaneous client error
* an HTTP error code if the server returned one (300-499 range)
* an httpfs error code if the httpfs provider returned one (8082xxxx range,
* it seems)
*
* hfs_do_simple: makes a request, collects all the data, gives it back
* hfs_do_chunked: makes a request, gives it to a callback function in chunks
* the callback does *not* own the data, and must not free it
* or keep a pointer to it; copy it if you want to keep it.
* This difference from the httpclient layer is ugly and may
* change at some point, even though that will cause a memory
* leak in all existing clients
* hfs_do_post_simple: POSTs a request, using a callback function to get chunks
* of data. The size must be known beforehand, an apparent
* unfortunate limitation of the ReplayTV httpfs server.
* writefile is the only (current/known) httpfs command that
* needs POST
*
* command: the httpfs command, one of: ls fstat volinfo cp mv rm create
* mkdir readfile writefile
* arguments are passed as tag/value pairs, NULL terminated.
* args for cp: src dest
* arg for create, fstat, ls, mkdir, rm, volinfo: name
* args for mv: old new
* args for readfile, writefile: name pos size
