little fixes

removed the warning if libidn isn't found

very minor output change

simplied the creation of new urls

%ld for long

int/long fix

Michael Benedict brought a fix that fills in the errorbuffer properly
when ares fails to resolve a name. This was fixed before but somehow has
fallen out again!

typo AGAIN

When using the icc compiler, we also ignore remark #1418 "external definition
with no prior declaration" since this is a habit we have in the code.

printf %s with plain 'char *', not unsigned ones to silence icc's picky
warnings

if no strerror_r prototype is found, we provide our own to prevent picky
compilers to warn

removed the unused 'len' variable, made use of the ptr pointer even if no
extra lib is used to prevent compiler warnings ("variable set but not used")
on that case

typecast the unsigned long to plain long to prevent compiler warnings

unused variable removed

use %ld to printf now.tv_sec

curlx.h is a header to add to the release archive(s)

fixed typo

Temporary disable the logic that runs gdb on a core dump, as it can't blindly
assume that the curl file is a proper binary, it is often a script file
produced by libtool.

hm, avoid division by zero more carefully with that new percentage math

Joe Halpin fixed the warning on the typecast from data pointer to function
pointer!

Gisle fixed the percentage to work, I adjusted it slightly to not as easily
overflow on 32bit filesize-systems

Gisle-fix: constified the 'interface' argument.

Gisle fix: curl_formparse is gone.

Gisle fixed: don't reference 'mem' if it's NULL.

initiate variables properly to default to no auth for server and proxy
