Remove ancient commentary from header.h

- history is interesting but public headers aren't the place for it
- "implemented soon after" from 2001 comments are hardly useful :)

  * a collection of data elements called tags. Each tag has a data type,
  * and includes 1 or more values.
  * 
- * \par Historical Issues
- *
- * Here's a brief description of features/incompatibilities that
- * have been added to headers and tags.
- *
- * - version 1
- *	- Support for version 1 headers was removed in rpm-4.0.
- *
- * - version 2
- *	- @todo Document version2 headers.
- *
- * - version 3	(added in rpm-3.0)
- *	- Added RPM_I18NSTRING_TYPE as an associative array reference
- *	  for i18n locale dependent single element tags (i.e Group).
- *	- Added an 8 byte magic string to headers in packages on-disk. The
- *	  magic string was not added to headers in the database.
- *
- * - version 4	(added in rpm-4.0)
- *	- Represent file names as a (dirname/basename/dirindex) triple
- *	  rather than as an absolute path name. Legacy package headers are
- *	  converted when the header is read. Legacy database headers are
- *	  converted when the database is rebuilt.
- *	- Simplify dependencies by eliminating the implict check on
- *	  package name/version/release in favor of an explict check
- *	  on package provides. Legacy package headers are converted
- *	  when the header is read. Legacy database headers are
- *        converted when the database is rebuilt.
- *	- (rpm-4.0.2) The original package header (and all original
- *	  metadata) is preserved in what's called an "immutable header region".
- *	  The original header can be retrieved as an RPM_BIN_TYPE, just
- *	  like any other tag, and the original header reconstituted using
- *	  headerLoad().
- *	- (rpm-4.0.2) The signature tags are added (and renumbered to avoid
- *	  tag value collisions) to the package header during package
- *	  installation.
- *	- (rpm-4.0.3) A SHA1 digest of the original header is appended
- *	  (i.e. detached digest) to the immutable header region to verify
- *	  changes to the original header.
- *	- (rpm-4.0.3) Private methods (e.g. headerLoad(), headerUnload(), etc.)
- *	  to permit header data to be manipulated opaquely through vectors.
- *	- (rpm-4.0.3) Sanity checks on header data to limit \#tags to 65K,
- *	  \#bytes to 16Mb, and total metadata size to 32Mb added.
- *	- with addition of tracking dependencies, the package version has been
- *	  reverted back to 3.
- * .
- *
- * \par Development Issues
- *
- * Here's a brief description of future features/incompatibilities that
- * will be added to headers.
- *
- * - Private header methods.
- *	- Private methods for the transaction element file info rpmfi may
- *	  be used as proof-of-concept, binary XML may be implemented
- *	  as a header format representation soon thereafter.
- * - DSA signature for header metadata.
- *	- The manner in which rpm packages are signed is going to change.
- *	  The SHA1 digest in the header will be signed, equivalent to a DSA
- *	  digital signature on the original header metadata. As the original
- *	  header will contain "trusted" (i.e. because the header is signed
- *	  with DSA) file MD5 digests, there will be little or no reason
- *	  to sign the payload, but that may happen as well. Note that cpio
- *	  headers in the payload are not used to install package metadata,
- *	  only the name field in the cpio header is used to associate an
- *	  archive file member with the corresponding entry for the file
- *	  in header metadata.
