Handle string length as size_t, consistently (almost always:))
Change function prototypes to accept size_t, where in the past
ulong or uint were used. change local/member variables to size_t
when appropriate.
This fix excludes rocksdb, spider,spider, sphinx and connect for now.
- Moving detection of the MY_CS_CSSORT, MY_CS_PUREASCII, MY_CS_NONASCII
flags of loadable collations from add_collation() in mysys.c
to my_cset_init_8bit() and my_coll_init_simple() in ctype-simple.c.
- Adding tests that these flags are set properly for loadable collations
- Moving LDML test related *.xml files from mysql-test/std_data/
to mysql-test/std_data/ldml/, as there will be more *.xml test files
The Item_string constructors called set_name() on the source string,
which was wrong because in case of UCS2/UTF16/UTF32 the source value
might be a not well formed string (e.g. have incomplete leftmost character).
Now set_name() is called on str_value after its copied
(with optionally left zero padding) from the source string.
- MDEV-6694 Illegal mix of collation with a PS parameter
Item_param::convert_str_value() did not set repertoire.
Introducing a new structure MY_STRING_METADATA to collect
character length and repertoire of a string in a single loop,
to avoid two separate loops. Adding a new class Item_basic_value::Metadata
as a convenience wrapper around MY_STRING_METADATA, to reuse the
code between Item_string and Item_param.
"mtr ctype_ldml" failed when compiled with "gcc -funsigned-char".
Changing the code not to depend on the signed/unsigned compiler defaults
for the "char" data type.

Added strings_def.h into strings library to be able to have a DBUG_ASSERT() version without _db_flush() call (as strings.a should not depend on dbug.a)

This patch provides performance improvements:
- send_fields() when character_set_results = latin1
is now about twice faster for column/table/database
names, consisting on ASCII characters.
Changes:
- Protocol doesn't use "convert" temporary buffer anymore,
and converts strings directly to "packet".
- General conversion optimization: quick conversion
of ASCII strings was added.
modified files:
include/m_ctype.h
- Adding a new flag.
- Adding a new function prototype
libmysqld/lib_sql.cc
- Adding quick conversion method for embedded library:
conversion is now done directly to result buffer,
without using a temporary buffer.
mysys/charset.c
- Mark all dynamic ucs2 character sets as non-ASCII
- Mark some dymamic 7bit and 8bit charsets as non-ASCII
(for example swe7 is not fully ASCII compatible).
sql/protocol.cc
- Adding quick method to convert a string directly
into protocol buffer, without using a temporary buffer.
sql/protocol.h
- Adding a new method prototype
sql/sql_string.cc
Optimization for conversion between two ASCII-compatible charsets:
- quickly convert ASCII strings,
switch to mc_wc->wc_mb method only when a non-ASCII character is met.
- copy four ASCII characters at once on i386
strings/conf_to_src.c
- Marking non-ASCII character sets with a flag.
strings/ctype-extra.c
- Regenerating ctype-extra.c by running "conf_to_src".
strings/ctype-uca.c
- Marking UCS2 character set as non-ASCII.
strings/ctype-ucs2.c
- Marking UCS2 character set as non-ASCII.
strings/ctype.c
- A new function to detect if a 7bit or 8bit character set
is ascii compatible.
This allows us to skip and speed up some very common character converts that MySQL is doing when sending data to the client
and this gives us a nice speed increase for most queries that uses only characters in the range 0x00-0x7f.
This code is based on Alexander Barkov's code that he has done in MySQL 6.0
