- While walking down the cache chain, we keep all upper caches locked.
- When we have to unlock -- when waiting for a busy page or reading a page in
-- we unlock completely, including the address space, and restart
vm_soft_fault().
- Folded fault_get_page() and fault_find_page() into one.
This simplifies and improves things considerably:
- We no longer need dummy pages.
- We no longer need vm_area::no_cache_change.
- #2710 is fixed, since we no longer hold the address space lock while
waiting.
* vm_soft_fault(): When we have found our page, we first check whether a page
is already mapped at the address. If it is already our page, we just change
its protection. If not, we unmap it first. Fixes race conditions when multiple
threads fault at the same address at the same time.
* fault_get_page(): When copying a read-only page from a lower cache, no longer
mark it active, since at least for the fault area it is shadowed from then on.
* vm_set_area_protection(): Fixed potential overflow for in the
vm_translation_map::protect() call.

* Create a file cache for created overlay nodes. It is unused and disabled, but
causes a vnode cache to be created. This is required for mapping a file, which
in turn is required for executables to be loaded. With that copied or newly
created executables should work on top of write_overlay. Will think about and
implement a more direct way of getting that cache later today.

B_UNSUPPORTED, resulting in true instead of false.

The target vnode in link and the toDir vnode in rename were passed directly,
meaning that an attribute_overlay vnode was handed to the next layer causing
crashes when moving/renaming a file on ISO-only CDs for example. Fixes#3885.

we want to ensure that we re-enumerate our environment when eventually writing
a new one as it has most probably changed.

pointing to a relocated directory, we now re-initialize the node we are
initializing with the first entry of the pointed at directory. This ought to be
the "." entry containing the proper flags, start block number and data length.
As per the specs we do only keep the file id or alternate name of the
placeholder and take everything else from the relocated directory.

it prints an even nicer stack trace. Not removing the code yet to make things
easier for architectures on which we don't have a userland yet.

OptionalPackages. This makes the content definition part in
AlternativeGCCArchive superfluous.
* Moved the cc and c++ wrapper scripts from src/bin to data/bin.
* Added build variable HAIKU_ADD_OPTIONAL_PACKAGES to add optional packages
-- the list can be separated by slashes to allow easier passing through
the shell.
* When invoking the sub-jam that builds the alternative GCC archive, we force
it to ignore the UserBuildConfigs and we enable the optional packages
enabled in the main jam.
* Reorganized /boot/develop:
- There's now an "abi" subdirectory containing a <arch>/<gcc>/ subdirectory
for each installed ABI-incompatible gcc version and a "current" symlink
pointed to the currently selected one.
- All ABI-dependent directories under /boot/develop/ (lib/x86, headers/cpp,
tools/gnupro) symlink into /boot/develop/abi/current.
- Changed BELIBRARIES to contain
/boot/develop/abi/current/library-paths/common instead of /boot/common/lib.
The former is a symlink to either /boot/common/lib or
/boot/common/lib/<gccVersion>. There's also a respective "home" symlink.
- Repackaged the optional binutils+gcc 2/4 packages accordingly. Also fixed
the obsolete /boot/beos/system/lib/libstdc++.so symlink in the gcc 4
package.
- The new structure allows to switch between compilers by changing the
/boot/develop/abi/current symlink. Added script setgcc to do that.

on an address in host-byte-order, not network-byte-order.
Basically this caused failure for all IP-traffic to any IP-address
where the last byte & 0xF0 == 0xe0.

This means that the workaround in mail_util.cpp of the mail kit could be
removed, but since I do not know if that should still support other versions
of BeOS, I have chosen to leave it alone.

the syscall. Anything beyond st_mtim was therefore not filled in. Fixes
the incorrectly shown creation times in Tracker.
* The BStatable::GetStat() solution was not sufficient yet. We still have to
provide the old GetStat() symbol for BNode and BEntry, since those could be
used by old applications/libraries. We also still have to implement the old
GetStat() slots in the derived classes, but don't need to implement it in
the base class (was purely virtual before and is private now).
* The old BStatable::_OhSoStatable1() slot function was not implemented
correctly. Calling the virtual function at the vtable slot obviously results
in an infinite recursion. The correct implementation would make use of the
Perform() method, but Be didn't provide one for BStatable, so we have to use
the old GetStat() method. Fixed#3960.
