When LF->CR+LF conversion causes an buffer truncation, supress the conversion (in case of unicode).
Handle SSL client certificate authentication in Windows Schannel security
support provider.

You have to place the certificate file postgresql.pfx (PFX or PKCS12 format)
in %APPDATA%\postgresql folder instead of postgresql.crt and postgresql.key
(I wasn't able to find the way to handle PEM format using Cryptography API
unfortunately).
You can create the file using the following command.
 openssl pkcs12 -export -in postgresql.crt -inkey postgresql.key
 -out postgresql.pfx (with empty password).
Change Windows installer build system for the next release.

Change to specify ProductCode for each version so as not to forget to change

Remove GSSAPI support by default
Concentrate the settings of Windows build system to an xml file and
build binaries or installers with reference to it.

	(configuration.xml)
		xml file to specify the setting of the build environment.
		It is automatically generated in winbuild folder as a copy
		of winbuild/configuration_template.xml when you invoke
		editConfiguration script firstly.

	winbuild/configuration.ps1	modules to handle the configuration file
	winbuild/editConfiguration.ps1	edit configuration file (GUI)
	winbuild/editConfiguration.bat	same as above with a minimized console window

	buildx86.ps1			build 32bit binary
	buildx64.ps1			build 64bit binary

	installer/buildx86-installer.ps1	build 32bit installer
	installer/buildx64-installer.ps1	build 64bit installer
