These helpers are core to btrfs, and in order to more easily sync various parts of the btrfs kernel code into btrfs-progs we need to be able to carry these helpers with us. However we want to have our own implementation for the helpers themselves, currently they're implemented in different files that we want to sync inside of btrfs-progs itself. Move these into their own C file, this will allow us to contain our overrides in btrfs-progs in it's own file without messing with the rest of the codebase.

2022-12-05btrfs: extend btrfs_dir_item type to store encryption statusOmar Sandoval
For directories with encrypted files/filenames, we need to store a flag indicating this fact. There's no room in other fields, so we'll need to borrow a bit from dir_type. Since it's now a combination of type and flags, we rename it to dir_flags to reflect its new usage. The new flag, FT_ENCRYPTED, indicates a directory containing encrypted data, which is orthogonal to file type; therefore, add the new flag, and make conversion from directory type to file type strip the flag. As the file types almost never change we can afford to use the bits. Actual usage will be guarded behind an incompat bit, this patch only adds the support for later use by fscrypt.

2022-12-05btrfs: setup qstr from dentrys using fscrypt helperSweet Tea Dorminy
Most places where we get a struct qstr, we are doing so from a dentry. With fscrypt, the dentry's name may be encrypted on-disk, so fscrypt provides a helper to convert a dentry name to the appropriate disk name if necessary. Convert each of the dentry name accesses to use fscrypt_setup_filename(), then convert the resulting fscrypt_name back to an unencrypted qstr. This does not work for nokey names, but the specific locations that could spawn nokey names are noted. At present, since there are no encrypted directories, nothing goes down the filename encryption paths.

2022-12-05btrfs: use struct qstr instead of name and namelen pairsSweet Tea Dorminy
Many functions throughout btrfs take name buffer and name length arguments. Most of these functions at the highest level are usually called with these arguments extracted from a supplied dentry's name. But the entire name can be passed instead, making each function a little more elegant. Each function whose arguments are currently the name and length extracted from a dentry is herein converted to instead take a pointer to the name in the dentry. The couple of calls to these calls without a struct dentry are converted to create an appropriate qstr to pass in. Additionally, every function which is only called with a name/len extracted directly from a qstr is also converted. This change has positive effect on stack consumption, frame of many functions is reduced but this will be used in the future for fscrypt related structures.
