[pacman-dev] add message() function call for use in *.install/.PKGINFO files

[Роман Кирилич]

Wow! I don't know what this code means (I'm not started digging
libalpm internals yet).
What I mean is something like this in .install file:

post_install()
{
  task_start("Generating initial ramdisk...")
  # some code here...
  task_end()
}

instead of this old bad way:

post_install()
{
  echo "Generating initial ramdisk..."
  # some code here...
  echo " done"
}

And like this:

post_install()
{
  message("Attention! Please change default config file before
restart!", "MTYPE_WARNING")
}

I'm talking about adding some predefined functions to "API" for PKGBUILDers.
