2026-02-24[DSC] Simplify file mapping to fix intermittent unrelocated pointersMark Rowe
The `FileAccessorCache`'s LRU eviction could discard a file's mapped data after slide info had already been applied to it. Future accesses to the file produced a fresh mapping, but failed to reapply the slide info. This could result in pointers not correctly being slid, such as in https://github.com/Vector35/binaryninja-api/issues/7689. The LRU cache existed to stay within OS file descriptor limits, since the old `MappedFile` held its fd open for the lifetime of the mapping. There's no real reason for it to hold the file descriptor open like this. Closing it after `mmap` is sufficient to avoid the file descriptor limits. `MappedFileRegion` replaces the combination of `FileAccessorCache`, `WeakFileAccessor`, and `MappedFileAccessor`. It closes the fd immediately after mmap, so all files can stay mapped without consuming descriptors, making the cache unnecessary. `MappedFileRegion` is owned directly by the `CacheEntry` for its full lifetime. Slide info is applied exactly once to each `MappedFileRegion`.

- Make `SharedCache::m_entries` a simple std::vector we never lookup based off the entry ID - Remove some old comments - Rename some old variables so that they are accurate - Fix compiler warnings - Remove some unneeded copying

slide info This improves performance by ~10x with the only real issue being a copy of the cache entry existing for each weak ref. Also fixes - Some old TODO's that are no longer relevant - Some function signatures not being const - FileAccessorCache not evicting enough accessors to fit under an adjusted cache size - Added a warning if we are over the global cache size in view initialization - Logger name not having a `.` in `SlideInfoProcessor::SlideInfoProcessor` - Re-added the accessor dirty check before applying slide info to fix https://github.com/Vector35/binaryninja-api/issues/6570
