globbing: curl glob counter mismatch with {} list use

The "fixed string" function wrongly bumped the "urlnum" counter which
made curl output the total number of URLs wrong when using
{one,two,three} lists in globs.

curl_easy_getinfo: Post CURLINFO_TLS_SESSION tidy up

1) Renamed curl_tlsinfo to curl_tlssessioninfo as discussed on the
mailing list.
2) Renamed curl_ssl_backend to curl_sslbackend so it doesn't follow our
function naming convention.
3) Updated sessioninfo.c example accordingly.
base64: Post basic validation tidy up

Due to the length checks introduced in commit e17c1b25bc33eb there is no
need to allow for extra space in the output buffer for a non-padded last
quantum.
base64: Extended validation to look for invalid characters

Extended the basic validation in commit e17c1b25bc33eb to return a
failure when invalid base64 characters are included.
base64: Post extended extended validation tidy up

Reduced the separate processing of the last quantum to be performed in
the main decoding loop and renamed some variables for consistency.
base64: Corrected typo from commit f3ee587775c88a

nss: use a better API for controlling SSL version

This change introduces a dependency on NSS 3.14+.
nss: put SSL version selection into separate fnc
nss: allow to use TLS > 1.0 if built against recent NSS

Bug: http://curl.haxx.se/mail/lib-2013-11/0162.html
nss: unconditionally require NSS_InitContext()

... since we depend on NSS 3.14+ because of SSL_VersionRangeSet() anyway
nss: make sure that 'sslver' is always initialized
tool_metalink: do not use HAVE_NSS_INITCONTEXT

... no longer provided by the configure script
pop3: Fix POP3_TYPE_ANY signed compilation warning

POP3_TYPE_ANY, or ~0, is written to pop3c->preftype in lib/pop3c.c, an
unsigned int variable.  The result of ~0 is -1, which caused a warning
due to writing a negative number to an unsigned variable.  To fix this,
make the expression ~0U so that its value is considered the unsigned
number UINT_MAX which is what SASL_AUTH_ANY does in curl_sasl.h.
