... the protocol is doing read/write a lot, so it needs to write often
even when downloading. A more proper fix could check for eactly when it
wants to write and only ask for it then.
Without this fix, an SMB download could easily get stuck when the event-driven
API was used.
Closes#2768
1. don't use "ULL" suffix since unsupported in older MSVC
2. use curl_off_t instead of custom long long ifdefs
3. make get_posix_time() not do unaligned data access
Fixes#2211Closes#2240

GCC 4.6.3 on travis complains:
smb.c: In function ‘get_posix_time’:
smb.c:725:13: error: declaration of ‘time’ shadows a global declaration
[-Werror=shadow]
Fix this by renaming the variable.
Add a new type of callback to Curl_handler which performs checks on
the connection. Alter RTSP so that it uses this callback to do its
own check on connection health.
Not all reply messages were properly checked for their lengths, which
made it possible to access uninitialized memory (but this does not lead
to out of boundary accesses).
Closes#1052

This header file must be included after all header files except
memdebug.h, as it does similar memory function redefinitions and can be
similarly affected by conflicting definitions in system or dependent
library headers.
Since we just started make use of free(NULL) in order to simplify code,
this change takes it a step further and:
- converts lots of Curl_safefree() calls to good old free()
- makes Curl_safefree() not check the pointer before free()
The (new) rule of thumb is: if you really want a function call that
frees a pointer and then assigns it to NULL, then use Curl_safefree().
But we will prefer just using free() from now on.

... as it never copies the trailing zero anyway and always just the four
bytes so let's not mislead anyone into thinking it is actually treated
as a string.

There is no need to set the 'state' and 'result' member variables to
SMB_REQUESTING (0) and CURLE_OK (0) after the allocation via calloc()
as calloc() initialises the contents to zero.
As Windows based autoconf builds don't yet define USE_WIN32_CRYPTO
either explicitly through --enable-win32-cypto or automatically on
_WIN32 based platforms, subsequent builds broke with the following
error message:
"Can't compile NTLM support without a crypto library."
Fixed an issue with the message size calculation where the raw bytes
from the buffer were interpreted as signed values rather than unsigned
values.

On some platforms curl would crash if no credentials were used. As such
added detection of such a use case to prevent this from happening.
