HttpReadResponse handles the details of reading a HTTP response It
takes and interactive parsing function and a response buffer. The
response buffer will hold at least the last 1/2 buffer of the data
stream. This allows errors to be handled by the calling routine.
Long responses should be parsed on the fly by the parsing callback.
HttpReadResponse handles find the content-length and header break.
Once the break is called, it will call the parsing callback so that it can
set findStr (which is NULL).
The findStr search is case insensitive if the first character of findStr
has distinct upper and lower cases (see toupper and tolower).
The callback is called with the buffer, the bytes in the buffer,
a pointer just past the findStr match, and a pointer to findStr.
The callback should then update findStr and searchStr; and return -2
for an error (abort message), 0 for success, and 1 for need more data.
findStr is expected to be a constant or static storage.
Before exit, the parsing callback is called one last time (with NULL
findStr and searchStr), so that it can do any cleanup.
Management of the buffer is done automatically by the movement of searchStr.
HttpReadResponse returns bytesInBuffer on success, -1 for IO error,
-2 for error returned by the parser.

/*
readWmapResponse handles the details of reading a HTTP response It
takes and interactive parsing function and a response buffer. The
response buffer will hold at least the last 1/2 buffer of the data
stream. This allows errors to be handled by the calling routine.
Long responses should be parsed on the fly by the parsing callback.
readWmapResponse handles find the content-length and header break.
Once the break is called, it will call the parsing callback so that it can
set findStr (which is NULL).
The findStr search is case insensitive if the first character of findStr
has distinct upper and lower cases (see toupper and tolower).
The callback is called with the buffer, the bytes in the buffer,
a pointer just past the findStr match, and a pointer to findStr.
The callback should then update findStr and searchStr; and return -2
for an error (abort message), 0 for success, and 1 for need more data.
findStr is expected to be a constant or static storage.
Before exit, the parsing callback is called one last time (with NULL
findStr and searchStr), so that it can do any cleanup.
Management of the buffer is done automatically by the movement of searchStr.
readWmapResponse returns bytesInBuffer on success, -1 for IO error,
-2 for error returned by the parser.
