* RzBin/ELF: avoid the creation of useless flags at 0
Use UT64_MAX as an error value for addresses like symbols, imports,
sections, etc., and do not create flags for those because they are not
meaningful. This is useful for imports that do not have an address in
the virtual/file space and for non-alloc sections (e.g. .comment).
* Changed behavior of `f` to only add flag if there is none
* Changed behavior of `f+` to add flag in any case
* Moved listing subcommands from `f` to `fl`
* Moved listing subcommands from `f.` to `f.l`
* Added subcommand `f.l*` to list all local flags in all functions
* Listing flags at the current offset became `fl.`
* Moved `f=` to `fl=`
* Old `fl` (flag length) now became `fL`
* Removed original `fe` commands
* Old `f?` (check if flag exists) now became `fe`
* Removed `fV` commands
* Removed `fn` commands in favor of `fl` and `asm.flags.real=true`
* Removed `fS` commands (`fSo` and `fSn`)
* `fo` became `fortune` and moved from "flags" to "shell" category
* Removed oldshell handlers of the `z` commands
* Disable `asm.bytes` by default
* Fix tests by adding `e asm.bytes=true` (1/n)
* Fix tests by adding (2/n)
* Fix tests by adding `e asm.bytes=true` (3/n)
* Fix tests by adding `asm.bytes=true` (4/n)
* Fix test by adding `asm.bytes=true` (5/n)
* Fix mostly all broken tests
* Attemp to fix the rzpipe test
* Attempt to fix the tests in `db/cmd/cmd_pipe`
* Fix tests again
* Fix cmd_pipe test
* Add a test where `asm.bytes` is false
