When uploading a big file (2,285,199,368 bytes) using WFileUpload widget, IE & Chrome seems working fine, however when using firefox 10.0, WT crashed due to firefox sending malformed header(Content-Length: --2009767703).

It appears that firefox mishandles signed/unsigned int32, wt should protect itself from crashing.

This problem happens on WT 3.2.0 (git commit 4e198c7dc5)

Reproducable with the widgetgallery example:
problem is at WebRequest.C::contentLength()

to create a 2G file:
dd if=/dev/zero of=output.dat bs=1G count=2

We should content lenght to be > 0, if not return 0 + log an error.
