[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so

Spelling fixes for usr.sbin/

Backout libinstall.a -> libpkg commit.

Discussed with: erwin, brooks, bapt

- Take libinstall.a out of pkg_install and make it a proper shared library.
- Rework the wrapper support to check libpkg version as well as pkg_install
version.
- Add libfetch to _prebuild_libs.
- There are no new features introduced.

Notes: the API is not stable, so basically, do not use libpkg in your
projects for now. Also there's no manpage for libpkg yet, because the API
will change drastically. I repeat, do not use libpkg for now.

Various fixes.

- Replace hardcoded INDEX version. [1]
- Fix a buffer overlap. [2]
- Remove empty package when fetching fails and -K is used. [3]
- Remove useless chmod2() after mkdtemp(3). [4]
- Replace mkdir(1) call with mkdir(2). [5]
- Get rid of some vsystem() calls.
- Switch from lstat(2) to open(2) in fexists().
- Try rename(2) in move_file() first.
- Bump PKG_INSTALL_VERSION to 20100401.

If the INDEX file cannot be opened, print the actual filename / path
pkg_version tried to open instead of just "INDEX" to make the actual
problem more clear (e.g. missing INDEX-8).

* pkg_version(1) exits if INDEX files is not found and -I is not
specified. The result is that the package will be listed with a '?'
as if it was not found within the INDEX file, so fix this behaviour.
* Remove trailing spaces.

Add -o/-O options to pkg_version:

-o Show the origin recorded on package generation instead of the
package name.

-O Only list packages whose registered origin is origin.

Based on PR: bin/78640
Submitted by: Marcus Grando <marcus at corp dot grupos.com.br>, flz

Add an -I option to pkg_version:

-I Use only the index file for determining if a package is out of
date. This is much faster than using the version number from a
port's Makefile, at the expense of potentially giving an incor-
rect result if the index file is out of date.

Without this option, the index file is only consulted if "make -V PKGNAME"
cannot be used.

Add a -q flag to pkg_version. It suppresses the output of <,=,>.
This makes it possible to "portupgrade `pkg_version -q -l '<'`".

- pkg_add spawns itself as argv[0] when installing dependent packages, to
enable the use as a port on older systems

- use absolute paths in all calls to external programs, to account for strange
PATH settings

- use INDEX or INDEX-5 depending on FreeBSD version, to enable the use on
FreeBSD 4.x as a port.

- conditionalize all 4.x/5.x differences on __FreeBSD_version, so that the
pkg_install tools can be kept in sync on 4.x and 5.x

- Bump PKG_INSTALL_VERSION

Minimal change to cause pkg_version to examine the new INDEX-5 file
instead of INDEX. This should be done better since this file name will
depend on the FreeBSD major version.

Vastly decrease amount of memory comsumed in the case when we have to read
ports/INDEX, by allocating eactly amount of memory necessary for storing
each particular entry, insdead of 4K per entry (more than 7000 entries -
go figure). Memory consumption went down to some 500K from some 30M.
