Add more opcodes.
Some minor API improvements.
Kill -Wswitch-enum as it's rather overzealous.
Add an --enable-analyze configure option.
Add Vim syntax files.
Remove pointless quoting.
Ignore *.gz.
Update man page.
Consistent use of double quotes.
Add internal headers to libparavm_SOURCES.

This is so that they get picked up in `make dist`.
Add Vim syntax files to EXTRA_DIST.
Sanitize paravm_LDADD.
Use manual name for pkg-config package name.

PACKAGE_NAME expanded to `paravm`, not `ParaVM`.
Use ${includedir}, not ${includedir}/paravm in pkg-config.
Generate the man page from configure.ac.
Fix naming guidelines in STYLE.
Move pkg-config files into a pc/ subdirectory.
Don't compile with -fborland-extensions and -fms-extensions.

We don't need these.
Clean up the common.h header.

* Remove attributes that we're unlikely to actually use in the public API.
* Document all of the attributes.
* Add attributes for starting/end declarations (yay C++!).
Add more error codes, and a function to turn them into strings.
