2021-06-24Everywhere: Use nothrow new with `adopt_{ref,own}_if_nonnull`Daniel Bertalan
This commit converts naked `new`s to `AK::try_make` and `AK::try_create` wherever possible. If the called constructor is private, this can not be done, so we instead now use the standard-defined and compiler-agnostic `new (nothrow)`.

2021-04-23AK: Rename adopt() to adopt_ref()Andreas Kling
This makes it more symmetrical with adopt_own() (which is used to create a NonnullOwnPtr from the result of a naked new.)
2021-04-22Everything: Move to SPDX license identifiers in all files.Brian Gianforcaro
SPDX License Identifiers are a more compact / standardized way of representing file license information. See: https://spdx.dev/resources/use/#identifiers This was done with the `ambr` search and replace tool. ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt *

2021-01-25Kernel: Hoist VM range allocation up to sys$mmap() itselfAndreas Kling
Instead of letting each File subclass do range allocation in their mmap() override, do it up front in sys$mmap(). This makes us honor alignment requests for file-backed memory mappings and simplifies the code somwhat.
2021-01-20Kernel+LibC: Turn errno codes into a strongly typed enumAndreas Kling
..and allow implicit creation of KResult and KResultOr from ErrnoCode. This means that kernel functions that return those types can finally do "return EINVAL;" and it will just work. There's a handful of functions that still deal with signed integers that should be converted to return KResults.
2021-01-15Kernel: Add anonymous files, created with sys$anon_create()Andreas Kling
This patch adds a new AnonymousFile class which is a File backed by an AnonymousVMObject that can only be mmap'ed and nothing else, really. I'm hoping that this can become a replacement for shbufs. :^)
