null_string wasn't known in libmysqld/lib_sql.cc, that caused compiler's error
i put the declaration of the null_string in mysql_priv.h and renamed it
to my_null_string to reduce the probability of name's intersections

Now it can work with any character set.

   on these)

  Typo fix: redundant "in"

  comp_err failed to compile error message file when a

  Bug fix

  There are some problems compiling with pure "configure"
  I need to fix it first.

sequence boundaries in functions LIKE and LOCATE in
the case of "binary" collation. Comparison was done
like if the strings were just a binary strings without
character set assumption.

embedded library
hash_insert renamed to my_hash_insert to avoid name intersection
with another libraries
is there better idea?

embedded library
missed memory freeing added

prepared statements in embedded library.
some fixes after testing

embedded library
some dirty places cleaned:

uint removed from mysql.h as Miguel suggested
empty_string renamed as my_empty_string to get rid of name's intersections
using embedded library

embedded library
I decided to get rid of #define mysql_some_function in mysql.h
It puzzles users and makes problems with dynamic libraries

Finally, there are only two functions left, that are covered with
the #define-s and it won't hurt performance at all
