wsrep_sst_common did not correctly set name for binlog index
file if custom binlog name was used and this name was
not added to script command line.
Added test case for both log_basename and log_binlog.
This fixed the MySQL bug# 20338 about misuse of double underscore
prefix __WIN__, which was old MySQL's idea of identifying Windows
Replace it by _WIN32 standard symbol for targeting Windows OS
(both 32 and 64 bit)
Not that connect storage engine is not fixed in this patch (must be
fixed in "upstream" branch)
This change removed 68 explict strlen() calls from the code.
The following renames was done to ensure we don't use the old names
when merging code from earlier releases, as using the new variables
for print function could result in crashes:
- charset->csname renamed to charset->cs_name
- charset->name renamed to charset->coll_name
Almost everything where mechanical changes except:
- Changed to use the new Protocol::store(LEX_CSTRING..) when possible
- Changed to use field->store(LEX_CSTRING*, CHARSET_INFO*) when possible
- Changed to use String->append(LEX_CSTRING&) when possible
Other things:
- There where compiler issues with ensuring that all character set names
points to the same string: gcc doesn't allow one to use integer constants
when defining global structures (constant char * pointers works fine).
To get around this, I declared defines for each character set name
length.
1) This commit implements reading all sections from configuration
files while looking for the current value of any server variable,
which were previously only read from the [mysqld.suffix] group and
from [mysqld], but not from other groups such as [mariadb.suffix],
[mariadb] or, for example, [server].
2) This commit also fixes misrecognition of some parameters when
parsing a command line containing a special marker for the end
of the list of options ("--") or when short option names (such
as "-s", "-a" and "-h arg") chained together (like a "-sah arg").
Such parameters can be passed to the SST script in the list of
arguments after "--mysqld-args" if the server is started with a
complex set of options - this was revealed during manual testing
of changes to read configuration files.
3) The server-side preparation code for the "--mysqld-args"
option list has also been simplified to make it easier to change
in the future (if needed), and has been improved to properly
handle the special backquote ("`") character in the argument
values.
Fixed bugs caused by inaccuracies in automatic merging
from other branches:
1) Authentication information is not removed from the connection
address, which causes some tests to fail;
2) wsrep_debug=on should be replaced with wsrep_debug=1;
3) Added missing "connection" lines to test result file;
4) Some tests have been corrected for Galera 4.x (10.4+).

and configuration.
1. Pass joiner's authentication information to donor together with address
in State Transfer Request. This allows joiner to authenticate donor on
connection. Previously joiner would accept data from anywhere.
2. Deprecate custom SSL configuration variables tca, tcert and tkey in favor
of more familiar ssl-ca, ssl-cert and ssl-key. For backward compatibility
tca, tcert and tkey are still supported.
3. Allow falling back to server-wide SSL configuration in [mysqld] if no SSL
configuration is found in [sst] section of the config file.
4. Introduce ssl-mode variable in [sst] section that takes standard values
and has following effects:
- old-style SSL configuration present in [sst]: no effect
otherwise:
- ssl-mode=DISABLED or absent: retains old, backward compatible behavior
and ignores any other SSL configuration
- ssl-mode=VERIFY*: verify joiner's certificate and CN on donor,
verify donor's secret on joiner
(passed to donor via State Transfer Request)
BACKWARD INCOMPATIBLE BEHAVIOR
- anything else enables new SSL configuration convetions but does not
require verification
ssl-mode should be set to VERIFY only in a fully upgraded cluster.
Examples:
[mysqld]
ssl-cert=/path/to/cert
ssl-key=/path/to/key
ssl-ca=/path/to/ca
[sst]
-- server-wide SSL configuration is ignored, SST does not use SSL
[mysqld]
ssl-cert=/path/to/cert
ssl-key=/path/to/key
ssl-ca=/path/to/ca
[sst]
ssl-mode=REQUIRED
-- use server-wide SSL configuration for SST but don't attempt to
verify the peer identity
[sst]
ssl-cert=/path/to/cert
ssl-key=/path/to/key
ssl-ca=/path/to/ca
ssl-mode=VERIFY_CA
-- use SST-specific SSL configuration for SST and require verification
on both sides

The test requires adaptation for MariaDB, which is done
in this patch. In addition, this patch includes a fix for
the SST script startup code that adds escaping for special
characters on the command line (in case they are contained
in the arguments to mysqld). The fix does not require
separate tests, as the required tests are already part
of the mtr suite for Galera.
We need to complete SST if both new and old start positions are
not same as initial positions. If they are initial positions
just set local uuid and seqno.
There were multiple problems here
* wsrep_trx_fragment_size should not be set when wsrep is disabled or provider is not loaded
* wsrep_trx_fragment_unit should not be set when wsrep is disabled or provider is not loaded
* wsrep_debug has no effect if wsrep is disabled or provider is not loaded
* wsrep_start_position should not be set when wsrep is disabled or provider is not loaded any other value than default
* wsrep_start_position should be changed only when we are joiner or initialized
* wsrep_start_position should be allowed to set only a value that exits, thus
we need to add error handling to wsrep_sst_complete
