b142b6f48e [#1367] fstree: Add size to file counter 
FSTree file counter used by writecache. As writecache has now only one
storage, so it is required to use real object size to get writecache
size more accurate than `count * max_object_size`.

b36a453238 [#970] fstree: Add build tag to enable generic version on linux 
Unless tested, generic version can start gaining bugs. With a separate
build tag we can have the best of both worlds:
1. Use optimized implementation for linux by default.
2. Run tests or benchmarks for both. Note that they are not actually
   run automatically now, but this is at leas possible.

abd502215f [#970] fstree: Move file locking to the generic writer 
It is not a part of FSTree itself, but rather a way to solve concurrent
counter update on non-linux implementations. New linux implementations
is pretty simple: link fails when the file exists, unlink fails when the
file doesn't exist.

Metabase test relied on this behaviour, so fix the test too.

fc31b9c947 [#970] fstree: Add linux-specific file writer using O_TMPFILE 
O_TMPFILE is implemented for all modern FSes and it's much easier and safer to
use. If application crashes in the middle of writing this file would be gone
and won't leave any garbage.

Notice that this implementation makes a different choice wrt EEXIST handling,
generic one always overwrites, while this one keeps the old data.

There is no real performance difference.

A directory is read and files are saved to a local variable. The iteration
over such files may lead to a non-existing files reading due to a normal SN
operation cycle and, therefore, may lead to a returning the OS error to a
caller. Skip just removed (or lost) files as the golang std library does in
similar situations:
