Some functions could by freak accident return an uninitialised value:

content_encoding.c: In function `Curl_unencode_deflate_write':
content_encoding.c:76: warning: `result' might be used uninitialized in this function
content_encoding.c: In function `Curl_unencode_gzip_write':
content_encoding.c:220: warning: `result' might be used uninitialized in this function

and

ssluse.c: In function `verifyhost':
ssluse.c:786: warning: `addrlen' might be used uninitialized in this function
ssluse.c:812: warning: `hostlen' might be used uninitialized in this function
ssluse.c:813: warning: `domainlen' might be used uninitialized in this function
ssluse.c:814: warning: `domain' might be used uninitialized in this function

A fix by initialising to 0 (CURLE_OK) would at last silence "gcc -Wall".
Or should the values be set to CURLE_LAST (or a new CURLE_UNEXP) to
indicate an unusual code-path?
