Add configuration option for Upgrade operation SigLevel

Add LocalFileSigLevel and RemoteFileSigLevel to control the signature
checking for "pacman -U <file>" and "pacman -U <url>" operations
respectively. The starting value for both these options is SigLevel,
if it is specified in the [options] section, or the built-in system
default. The specified values override and/or supplement this initial
value. Note there is no distinction between setting "Required" and
"PackageRequired" as there are no database options for Upgrade
operations.

makepkg: make $pkgdir non-accessible during build()

The idea of having separate build() and package() functions is that
build() is run as a normal uses and package() as (fake)root.  Any
files placed in $pkgdir during build() can have the wrong permissions.

Restrict access to $pkgdir during build() - unless there is no package()
function.

Also, set $pkgdir to something "useful" during build().  For split
packages, this uses "<path>/pkg/$pkgbase" because it is not obvious
which $pkgdir is being referred to.

doc: update PKGBUILD man page

Rearrange the functions section of the PKGBUILD man package. Clarify
that the package() function is a requirement and the rest are all
optional.  Note that $pkgdir should only be used in the package()
function.
