From Sergei Linev:
1. New static methods to set/get time formatting in TOracleServer
2. Move float format constant for TBufferSQL2 to TSQLServer
3. Use that format in several other appropriate places like TODBCStatement, TOracleRow and so on.
4. Replace sprintf to snprintf calls in several places.

From Sebastien Ponce and Sergei Linev:
Two little extensions to the ROOT classes dealing with SQL and more
precisely ORACLE Statement and Server :
  - added possibility to connect to ORACLE in object mode, by adding to
    the connection URL an argument like "?ObjectMode=yes"
  - added vector interfaces for numeric data in the sqlStatement class
    and its implementation in ORACLE

From Andrew Savchenko:
ROOT can not be compiled with gcc-4.3.
Some ROOT source files doesn't contain required #include directives,
for example, they use strlen(), but #include <string.h> is missed or
malloc() is used and #include <stdlib.h> is missed. 

Earlier versions of gcc allowed some headers to be included implicitly,
but issued a warning (-Wimplicit-function-declaration). Newer one,
gcc-4.3 denies such silly behaviour: all required headers must be explicitly
included. 

Attached patch fixes this. Also it fixes another issue, which disallows
ROOT to compile under gcc-4.3: C functions don't belong to namespace std,
so expressions like std::memcpy() are no longer valid and plain memcpy()
should be used instead.

Set property svn:eol-style LF on all source and Makefiles. This should avoid
problems with Win32 line endings ending up in the repository. All MS tools
support LF eols fine.

From Sergey Linev:
1. New virtual method TSQLStatement::SetMaxFieldSize(). It implemented for now only for Oracle and
   specifies maximum size in bytes, which should be used for field in read/write operation.

2. Improved implementation of TOracleStatement::GetBinary method. Now not only BLOB, but also
   CLOB, LONG, BFILE, CFILE Oracle datatypes are supported for reading. Fow now BFILE and CFILE
   not supported for writing.

From Sergey Linev:
1. Support of date/time/date&time/timestamp data introduced in TSQLStatement
   All such data now can be accessed without text conversion.
   The following methods can be used:

   SetTime()/GetTime() - only time (hour:min:sec),
   SetDate()/GetDate() - only date (year-month-day),
   SetDatime()/GetDatime() - date and time
   SetTimestamp()/GetTimestamp() - timestamp with seconds fraction
   For some of these methods TDatime type can be used as parameter / return value.
   Be aware, that TDatime supports only dates after 1995-01-01.
   There are also methods to get separately year, month, day, hour, minutes and seconds.

2. Support of binary data in TSQLStatement
    Most of modern data bases support just binary data, which is
    typically has SQL type name 'BLOB'. To access data in such
    columns, GetBinary()/SetBinary() methods should be used.
    Current implementation supposes, that complete content of the
    column must be retrieved at once. Therefore very big data of
    gigabytes size may cause a problem.

From Sergey Linev:
1. Support for MySQL version 3.2.x and 4.0 enabled again. For that old MySQL versions TSQLStatement is not supported.
2. Small fix in TSQLFile. With old MySQL versions it does not try to use TSQLStatement class.
3. Enabling/disabling error output for TSQLStatement class.
4. Fix in error handling in TMySQLServer::Statement() method. Previousely error code was not correctly stored.

2. Small changes in TSQLServer class

From Sergey Linev:
1. New methods of TSQLServer class (also for Oracle, MySQL, ODBC):
     Exec() - execute query which does not produce any result
     GetTablesList() - return list of tables names in data-base independent form
     IsTableExists() - check if table of given name exists
     GetTableInfo() - returns instance of TSQLTableInfo with list of columns.
2. New methods of TSQLStatement class (also for Oracle, MySQL, ODBC):
     IsNull() - checks, if field value is NULL
     SetNull() - sets parameter value to NULL


New TSQLTableInfo contains information about table and table columns.
For MySQL additional information like engine type, creation and last update time is provided


New TSQLColumnInfo class contains information about single column from SQL table
Has following methods:
   GetTypeName() - field type name in string form as it is reported by correspondent
          database method. Some databases providing full type name like "numeric(20)",
          other showing only "NUMERIC". As a result, one cannot use this string directly
          to create new field of similar types in other table
   IsNullable() - says if field value can be NULL or not
   GetSQLType() - returns kind of sql type. Possible values:
      TSQLServer::kSQL_NONE        data type unknown
      TSQLServer::kSQL_CHAR        CHAR(n) - string with fixed length n
      TSQLServer::kSQL_VARCHAR     VARCHAR(n) - string with variable length upto n
      TSQLServer::kSQL_INTEGER     INTEGER, INT, TINYINT - any integer types
      TSQLServer::kSQL_FLOAT       FLOAT - float value
      TSQLServer::kSQL_DOUBLE      DOUBLE - double precision value
      TSQLServer::kSQL_NUMERIC     NUMERIC(n,s), NUMBER(n,s) - numeric values with length and precion
      TSQLServer::kSQL_BINARY      BLOB, VARBINARY  - binary data (vriable or fixed size)
      TSQLServer::kSQL_TIMESTAMP   TIMESTAMP - time and date stamp
   GetSize() - size of field in database. -1 if not known.
   GetLength() - length argument in type declaration like CHAR(len) or NUMERIC(len), -1 if not defined
   GetScale() - second argument in declarations like NUMERIC(len, s), -1 if not defined
   GetSigned() - is type signed(==1) or unsigned(==0), -1 if not defined

From Sergei Linev:
1. Error handling is introduced. Now TSQLServer/TSQLStatement returns error code - GetErrorCode()
   and message - GetErrorMsg() of last operation.
   If desired, error output can be suppressed for TSQLServer. Correspondent changes done in implementation
   for Oracle, MySQL, ODBC
2. New methods of TSQLServer class for transactions control: StartTransaction() / Commit() / Rollback().
   As desfault implmenetaion in TSQLServer class they corresopnd to SQL "START TRANSACTION", "COMMIT", "ROLLBACK" queries.
   For Oracle, MySQL and ODBC specific implmentaion were done while there special methods should be called.
3. Some other new methods of TSQLServer class:
     IsSupportStatement() - return kTRUE if plugin has TSQLStatement implementation
     GetMaxIdentifierLength() - return maximum allowed length of identifiers
4. Bugfix in TODBCRow class
