Import revision 48931 from the v5-34-00 patch branch:
Add the concept of implicit rules to (centrally) support automatic translation of
STL collection from numeric type to other numeric type or for when the contained
class has some rules. Currently enabled only when the target is an std::vector.
Implement the transformation from STL container of numeric to any other numeric
type (both in TGenCollectionStreamer and TStreamerInfo[Actions]).
Migrate more of the conversions to TStreamerInfoActions.
Fix the Conversion of a Double32 or Float16 inside a collection of object to another
type (the previous implemetation was not supporting the customization of the factor
nor the number of bits).
Add TBuffer::ReadFastArrayWithNbits and WithFactor for use in the StreamerInfo Actions.
TStreamerInfoActions:
Introduce WithFactorMarker and NoFactorMarker to allow for less code duplicaton when
supporting Float16_t and Double32_t.
Replace the collection-memberwise action from loop over simple operation to using
ReadFastArray (to be compatible with TBufferXML).

Import revision 48921 from the v5-34-00 patch branch:
Improve performace of reading a vector of non-class type by 25% (i.e. std::vector<int>).
The code to apply the same improvement to other container type is in place but is not
enabled yet as the 'better' solution avoid creating a temporary array to read in the
value via Read[Fast]Array, however the avoid the call to Read[Fast]Array breaks
the XML streaming (which uses Read[Fast]Array to insert the <Array> tag around the
element). See for example VectorLooper::ReadCollectionBool ...

Import revision 48911 from the v5-34-00 patch branch:
Add the Action function for trivial conversion.
Refactor the creation of the ConfiguredAction for collection (using 3 classes with function templates) that are used in the unique generator functions. This reduces code duplication.

From Sergey:
There are Oracle native data types, which not yet supported by TOracleRow
class.
Patch provides support for BDOUBLE and BFLOAT types.

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 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.

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 Sergei Linev:
Main performance improvement are these two lines.
fStmt->setPrefetchRowCount(1000);
fStmt->setPrefetchMemorySize(1000000);
It increases default buffers, which are about 8K and read much faster.
For my example it runs 3 times faster, for other application it can be 4-5 times.
Second patch is required for treatement of integers out of normal integer range (long long or unsigned int).
I replace string -> int -> string conversion by just copying string to buffer. For the floats it is not working,
while Oracle text format differs from C++ format.

From Yan Liu and Shaowen Wang:
This is the first version of the new oracle plugin.
To build this plugin one needs to install the following
Oracle InstantClient rpms:
oracle-instantclient-basic-10.1.0.3-1
oracle-instantclient-devel-10.1.0.3-1
And the following environment variables in your .[bash_]profile:
export ORACLEINCDIR=/usr/include/oracle/10.1.0.3/client
export ORACLELIBDIR=/usr/lib/oracle/10.1.0.3/client/lib
export LD_LIBRARY_PATH=$ORACLELIBDIR:$LD_LIBRARY_PATH
