started support for unicode on the wire in smbd. Using a very similar method to what was used in the client I now have session setup and tconx working. Currently this is enabled with SMBD_USE_UNICODE environment variable. Once the code is complete this will become a smb.conf option. (This used to be commit 7684c1e67294266d018c6f0cab58f1a9d797174f)

r23726: Explicitly pass down the FLAGS2 field to srvstr_pull_buf. The next checkin will pull this up to srvstr_get_path. At that point we can get more independent of the inbuf, the base_ptr in pull_string will only be used to satisfy UCS2 alignment constraints.

make sure we don't walk past the end of the current SMB buffer when pulling a string this might explain a serious filename corruption bug that Quantum QA spotted (This used to be commit a877eae24becad9e0cd5b33ffe0916a20d5ba227)

/* pull a string from the smb_buf part of a packet. In this case the
string can either be null terminated or it can be terminated by the
end of the smbbuf area
*/
String handling parinoia fixes. This patch enables the compile-time checking of strings assable by means of sizeof(). (Original code had the configure check reversed). This is extended to all safe_strcpy() users, push_string and pull_string, as well as the cli and srv derivitives. There is an attempt to cap strings at the end of the cli buffer, and clobber_region() of the speified length (when not -1 :-). Becouse of the way they are declared, the 'overmalloc a string' users of safe_strcpy() have been changed to use overmalloc_safe_strcpy() (which skips some of the checks). This whole ball of mud worked fine, until I pulled out my 'fix' for our statcache. When jeremy fixes that, we should be able to get back to testing this stuff. This patch also includes a 'marker' of the last caller to clobber_region (ie, the function that called pstrcpy() that called clobber_region) to assist in debugging problems that may have smashed the stack. This is printed at smb_panic() time. (Original idea and patch by metze). It also removes some unsused functions, and #if 0's some others that are unused but probably should be used in the near future. For now, this patch gives us some confidence on one class of trivial parsing error in our code. Andrew Bartlett (This used to be commit 31f4827acc2a2f00399a5528fc83a0dae5cebaf4)
