pool: fix deadlock with --max-memory and multipart transfers

Because multipart transfers can need more than one buffer to complete, if transfers was set very high, it was possible for lots of multipart transfers to start, grab fewer buffers than chunk size, then deadlock because no more memory was available. This fixes the problem by introducing a reservation system which the multipart transfer uses to ensure it can reserve all the memory for one chunk before starting.

-## Keeping a backend or command out of tree
-
-Rclone was designed to be modular so it is very easy to keep a backend
-or a command out of the main rclone source tree.
-
-So for example if you had a backend which accessed your proprietary
-systems or a command which was specialised for your needs you could
-add them out of tree.
-
-This may be easier than using a plugin and is supported on all
-platforms not just macOS and Linux.
-
-This is explained further in https://github.com/rclone/rclone_out_of_tree_example
-which has an example of an out of tree backend `ram` (which is a
-renamed version of the `memory` backend).

-convmv supports advanced path name transformations for converting and renaming files and directories by applying prefixes, suffixes, and other alterations.
-
-`+transform.Help()+`Multiple transformations can be used in sequence, applied in the order they are specified on the command line.
-
-The ¡--name-transform¡ flag is also available in ¡sync¡, ¡copy¡, and ¡move¡.
-
-## Files vs Directories
-
-By default ¡--name-transform¡ will only apply to file names. The means only the leaf file name will be transformed.
-However some of the transforms would be better applied to the whole path or just directories.
-To choose which which part of the file path is affected some tags can be added to the ¡--name-transform¡.
-
-| Tag | Effect |
-|------|------|
-| ¡file¡ | Only transform the leaf name of files (DEFAULT) |
-| ¡dir¡ | Only transform name of directories - these may appear anywhere in the path |
-| ¡all¡ | Transform the entire path for files and directories |
-
-This is used by adding the tag into the transform name like this: ¡--name-transform file,prefix=ABC¡ or ¡--name-transform dir,prefix=DEF¡.
-
-For some conversions using all is more likely to be useful, for example ¡--name-transform all,nfc¡.
-
-Note that ¡--name-transform¡ may not add path separators ¡/¡ to the name. This will cause an error.
-
-## Ordering and Conflicts
-
-* Transformations will be applied in the order specified by the user.
-    * If the ¡file¡ tag is in use (the default) then only the leaf name of files will be transformed.
-    * If the ¡dir¡ tag is in use then directories anywhere in the path will be transformed
-    * If the ¡all¡ tag is in use then directories and files anywhere in the path will be transformed
-    * Each transformation will be run one path segment at a time.
-    * If a transformation adds a ¡/¡ or ends up with an empty path segment then that will be an error.
-* It is up to the user to put the transformations in a sensible order.
-    * Conflicting transformations, such as ¡prefix¡ followed by ¡trimprefix¡ or ¡nfc¡ followed by ¡nfd¡, are possible.
-    * Instead of enforcing mutual exclusivity, transformations are applied in sequence as specified by the
-user, allowing for intentional use cases (e.g., trimming one prefix before adding another).
-    * Users should be aware that certain combinations may lead to unexpected results and should verify
-transformations using ¡--dry-run¡ before execution.
-
-## Race Conditions and Non-Deterministic Behavior
-
-Some transformations, such as ¡replace=old:new¡, may introduce conflicts where multiple source files map to the same destination name.
-This can lead to race conditions when performing concurrent transfers. It is up to the user to anticipate these.
-* If two files from the source are transformed into the same name at the destination, the final state may be non-deterministic.
-* Running rclone check after a sync using such transformations may erroneously report missing or differing files due to overwritten results.
-
-To minimize risks, users should:
-* Carefully review transformations that may introduce conflicts.
-* Use ¡--dry-run¡ to inspect changes before executing a sync (but keep in mind that it won't show the effect of non-deterministic transformations).
-* Avoid transformations that cause multiple distinct source files to map to the same destination name.
-* Consider disabling concurrency with ¡--transfers=1¡ if necessary.
-* Certain transformations (e.g. ¡prefix¡) will have a multiplying effect every time they are used. Avoid these when using ¡bisync¡.
