Mike Kaganski a2c3ef6d81 Move BSTR wrapper to systools, and fix some wrong BSTR uses
BSTR is documented [1] to be prefixed by a 32-bit integer specifying
its length *in bytes* (not characters), so passing wchar_t* as BSTR
is wrong, and the length member of rtl_uString can't substitute the
proper BSTR length, since rtl_uString::length specifies length in
characters. Any code taking BSTR and using SysStringLen to get its
length would only get half of the passed OUString data.

In dbaccess/source/ui/dlg/adodatalinks.cxx, the abovementioned
error was implemented. OTOH, OLEVariant::getByteSequence() in
connectivity/source/drivers/ado/Aolevariant.cxx passed BSTR from
tagVARIANT to ctor of OLEString, which resulted in the BSTR being
freed in both dtors of OLEString and OLEVariant (the latter calls
VariantClear, which itself clears string when vtfield is VT_BSTR).

Miscellaneous Modules

This module contains a grab-bag of unrelated miscellaneous libraries, none of which is an extension.

Application Online Update Checking

When we start LO, first InitUpdateCheckJobThread is created, via UpdateCheckJob::execute() (from extensions/source/update/check/updatecheckjob.cxx), as a reaction to a onFirstVisibleTask event. It waits 25 seconds (so that it does not interfere with the startup itself), and then calls UpdateCheck::initialize() (from extensions/source/update/check/updatecheck.cxx).

This creates one more thread, UpdateCheckThread, that regularly checks whether we have reached the time when we should ask for the update. If yes, asks for that, and shows the download button in the menu (if the new update is available).

OLE Automation Bridge

A bridge between "OLE automation" and UNO, so you can use UNO services from JScript, VBScript, etc.

https://www.openoffice.org/udk/common/man/spec/ole_bridge.html

See udkapi/com/sun/star/bridge/oleautomation/ApplicationRegistration.idl

This is initialized in Desktop::Main() in Desktop::OpenClients_Impl() by creating the service com.sun.star.bridge.OleApplicationRegistration, which is implemented by OleServer_Impl.

See extensions/source/ole/

ActiveX Control

This allows embedding LO into a Win32 application as an ActiveX control.

See extensions/source/activex/

Spotlight Provider

On macOS, this allows indexing ODF documents with Spotlight.

See extensions/source/macosx/spotlight/

Scanner Support

You can scan from LibreOffice, using platform specific backends like TWAIN/SANE.

See extensions/source/scanner/
