Use 'TCHAR *' for local attribute variable rather than 'char *'.

Use 'TCHAR *' for local DN variable rather than 'char *'.

Due to the recent modifications this function is no longer used.

ldap.c:98: warning: extra tokens at end of #endif directive

ldap.c:802: warning: comparison between signed and unsigned integer
            expressions

The unescapped DN was not freed after a successful character conversion.

ldap.c:738: error: macro "LDAP_TRACE" passed 2 arguments, but takes
            just 1

ldap.c:89: warning: extra tokens at end of #endif directive

As host.name may be encoded use dispname for infof() failure messages.

As we get the length for the DN and attribute variables, and we know
the length for the line terminator, pass the length values rather than
zero as this will save Curl_client_write() from having to perform an
additional strlen() call.

curl_ntlm_core.c:146: warning: passing 'DES_cblock' (aka 'unsigned char
                      [8]') to parameter of type 'char *' converts
                      between pointers to integer types with different
                      sign

Rather than duplicate the code in setup_des_key() for OpenSSL and in
extend_key_56_to_64() for non-OpenSSL based crypto engines, as it is
the same, use extend_key_56_to_64() for all engines.

Having files named endian.[c|h] seemed to cause issues under Linux so
renamed them both to have the curl_ prefix in the filenames.

lib1900.c:182: (style) Array index 'handlenum' is used before limits
               check

Bug: https://github.com/bagder/curl/pull/133

To allow the little endian functions, currently used in two of the NTLM
source files, to be used by other modules such as the SMB module.
