Subject: [PATCH] Avoid sign extension warnings from coverity

 src/vncconnection.c:3082: sign_extension:
 Suspicious implicit sign extension: "height" with type "unsigned short"
 (16 bits, unsigned) is promoted in "rowlen * height" to type "int"
 (32 bits, signed), then sign-extended to type "unsigned long"
 (64 bits, unsigned). If "rowlen * height" is greater than 0x7FFFFFFF,
 the upper bits of the result will all be 1.

The 'rowlen' variable is initialization from the unsigned width
variable, so should have used uint instead of int.

(cherry picked from commit c3e5d23d67c9a209f127caab7843d94a91031a5f)
