package.bbclass: add getter of additional metadata

Two variables are searched for value of additional package metadata:

  * PACKAGE_ADD_METADATA_<PKGTYPE>
  * PACKAGE_ADD_METADATA

First found variable with defined value wins.

<PKGTYPE> is a parameter of getter and expected to be a distinct name
of specific package type. For example: 'DEB' or 'RPM'.

Variable can contain multiple [one-line] metadata fields, separated by
literal sequence '\n'. Separator can be redefined through variable flag
'separator'. Getter returns found value with separator replaced with
newline character.

As side-effect, searched variables acquired flags 'type' (equals to
'list') and 'separator'.

package_{ipk, deb, rpm}.bbclass: support additional user-defined metadata

Additional metadata from user-defined variable is written into
control/spec file of binary package.

Three variables are searched for adiitional package metadata:

  * PACKAGE_ADD_METADATA_<PKGTYPE>_<PN>
  * PACKAGE_ADD_METADATA_<PKGTYPE>
  * PACKAGE_ADD_METADATA

First found variable with defined value wins.

<PN> is a package name. <PKGTYPE> is a distinct name of specific
package type:

  * IPK for .ipk packages
  * DEB for .deb packages
  * RPM for .rpm packages

Variable can contain multiple [one-line] metadata fields separated by
literal sequence '\n'. Separator can be redefined through variable flag
'separator'. In package control/spec file separator is replaced by
newline character.

package.bbclass: add SHLIBSSEARCHDIRS to define where to search for shlib providers

* when package contains some files matching "^.*\.so", but in directory
  not default linker search paths (e.g. /opt/package/bundled-lib/libfoo.so)
  don't register it as libfoo provider, because it's possible that there
  is different package providing libfoo.so in ${libdir} and that would
  be better shlib provider for other packages to depend on
* recipes providing libs intentionally in some other directory can
  define own SHLIBSSEARCHDIRS value
