First round of 64-bit safety fixes in the kernel.

* Most of this is incorrect printf format strings. Changed all strings
causing errors to use the B_PRI* format string definitions, which
means the strings should be correct across all platforms.
* Some other fixes for errors, casts required, etc.

Cleanup system-revision stuff.
* move system_revision.h to headers/private/libroot
* unify libroot's get_system_revision() (the one I introduced recently) with kernel's
get_haiku_revision(), the function is now called get_haiku_revision() in the kernel
and __get_haiku_revision() in libroot
* system_revision.c is now being built as part of libroot and as part of the kernel
* adjusted all callers of get_system_revision() accordingly

Fix the larger problem that was hiding behind the build problem of set_haiku_revsion on FreeBSD:
* the length of the sHaikuRevision character array symbol needs to be set explicitly,
as using either _SYS_NAMELEN or sizeof(utsname::version) will only return the values
for the host, which may not match ours, thus potentially causing problems when using
sHaikuRevision
* add headers/private/system_revision.h which defines SYSTEM_REVISION_LENGTH to 128
* adjust definitions of sHaikuRevision in libroot and kernel accordingly
utsname::version is shorter than SYSTEM_REVISION_LENGTH, but that doesn't cause any harm
until we have indeed switched to a DVCS (in which case longer revision strings will be
cut off by 'uname').

Remove reference to SVN, now that revision is a VCS-agnostic string...


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@41394 a95241bf-73f2-0310-859d-f6bbb57e9c96

Switch haiku-revision from uint32 to string, as that's going to be required soon, no matter if we switch to Git or Mercurial
* increase _SYS_NAMELEN defined in sys/utsname.h to 128 to allow long(ish) revisions
* sHaikuRevision is now a static character array (in both libroot and kernel)
* adjust build tool set_haiku_revision to write the revision as string

The wrong ID was being passed into _SendMessage(), leading to all thread
property change notifications being sent as having occurred for the team's
main thread.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39865 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented a generic system watching mechanism with a userland API. Currently
only a few events can be watched (team creation/deletion/exec, thread creation/
deletion/name changes). The functions start_system_watching()/
stop_system_watching start/stop watching events.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39862 a95241bf-73f2-0310-859d-f6bbb57e9c96

Add gcc version information to kdl info command. This could help debugging in some cases and fixes #3240.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37562 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed more address types related issues. Mostly printf() or comparison
warnings, but also some oversights from earlier changes.

dump_info(): We can't use use cpu_get_active_time() in the kernel debugger as
it tries to acquire the thread spinlock.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35657 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Moved the VM headers into subdirectory vm/.
* Renamed vm_cache.h/vm_address_space.h to VMCache.h/VMAddressSpace.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34449 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added system_info::abi field. It contains the system's ABI version, which
might be different from that of the caller (on hybrid builds).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30858 a95241bf-73f2-0310-859d-f6bbb57e9c96

* The "info" KDL command now also dumps the built-in SVN revision.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28153 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Implemented a (private for now) get_system_info_etc() call, that can retrieve
various system information.
* Implemented retrieving some VM stats via this call.
* The VM now maintains a page fault counter, and sets system_info::page_faults
accordingly.
* Added a (pretty simple) "vmstat" command line app.
* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27597 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Moved the incrementing/decrementing of vm_page::wired_count into
dedicated functions.
* Introduced gMappedPagesCount variable which counts the total number of
physical pages that are mapped.
* Added vm_page_get_stats() which fills in the memory related part of
the system_info structure. Used and cached pages are computed
differently, now. The "available" (== not committed) memory is no
longer used for the computation as it doesn't say anything about the
actually used/free pages (with swap support enabled it is even
less meaningful, since we first commit swap space when possible).
We do also consider the memory used by the block cache as cached
pages, now. All in all these changes should fix the memory statistics
reported by get_system_info(), IOW bug #2574.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26837 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Reenabled used page reporting based on vm_available_memory().
* Prettyfied memory info in the sysinfo app.
* Minor cleanup.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24746 a95241bf-73f2-0310-859d-f6bbb57e9c96

Use the old calculations for used_pages for the time being until the issue with sAvailableMemory is resolved.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24615 a95241bf-73f2-0310-859d-f6bbb57e9c96

Applied patch by Rene Gollent:
* Add a cached_pages field to the system_info structure, and change the
meaning of the used_pages field to not include cached pages.
* Provide the needed info using the new calls vm_get_available_memory(),
and vm_page_num_available_pages().


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24571 a95241bf-73f2-0310-859d-f6bbb57e9c96

Applied patch by Vasilis:
* Fixed various warnings with GCC4 due to the double sHaikuRevision line.
* Turned system_info.c to a C++ file.
* Minor cleanup.
