Sigh. Another forgotten header file.

Diff to previous 1.17 (colored)
Use a dedicated struct mbr to hold the GPT protective MBR, either the one read from disk or the default one created when initializing GPT. Simplifies logic, eliminates MBR_init_GPT() and demotes MBR_protective_mbr() to a helper function called from GPT_read(). Nuke an unused variable in passing. No intentional functional change.

Make GPT_read() obtain and validate the on-disk MBR itself, via MBR_read(), and report success/failure. Simplifies logic and makes clearer that the protective MBR is a required part of a GPT. With the standardization on 0/-1 return values for helper functions, rename 'valid' to 'error' in GPT_read() to make logic less mind bending. No functional change.

No need for separate b_sectors, b_offset and b_type variables. We have struct prt to hold this info in one place. Construct a struct prt to hold the boot partition information and stash it in the struct disk for both MBR and GPT to access as needed. Move the blocks to sectors conversions into DISK_open() with all of its geometry friends. No intentional functional change.

Toss 'const' in anywhere the compiler doesn't complain about, thus identifying places that *should* be const but currently aren't and preventing the rot from spreading further while those issues are dealt with. No functional change.

Add another epicycle to -A processing that ensures ONLY the partition table is changed. Not the GPT header. Not the MBR. And only write back as much partition table information as the header claims to have room for. At a minimum should make -A safer when operating on the Apple M1 GPT. A major overhaul of this code is urgently needed before someone sneezes too hard in its vicinity. Feedback kettenis@ & ok deraadt@

Ensure that the '-i' command line option and the 'reinit [mbr]' editing commnd completely remove any existing on-disk GPT header when writing the MBR. '-ig'/'reinit gpt' must be used to create GPT format. Previous interactions between '-i', '-b' and overly clever 'reinit' produced surprising, inconsistent and incorrect behaviour. ok deraadt@ kettenis@

GPT_get_header() and GPT_get_partition_table() are only used in gpt.c. Move declarations and rename to get_header() and get_partition_table(). No functional change.

No need to pass the location of the partition table to GPT_get_partition_table() since the global 'gh' knows where it is. Fixes a couple of missing letoh64() calls by eliminating the need for them.

Revamp the display of GPT information, hiding less important information under the '-v' flag. This brings the GPT display more into line with the MBR display and simplifies and hardens the parsing of the partition info in the install scripts. Original problem with install scripts parsing hand edited GPT information reported by Valere Monseur via bugs@. Man page fixes and tweaks from jmc@. Install script changes tested & ok rpe@.

Move zapping of invalid GPT data into GPT_get_gpt() rather than returning a value to tell callers to zap it. Use consistant idiom to check for the presence of a GPT (check gh.gh_sig). When zapping GPT, always zap both the header and partition table just for paranoia's sake.

Move from opening/closing disk for every i/o to opening the disk once and saving the fd in the global 'disk' structure. Stop passing around fd's and just use the global. Makes pledge() feasible. Prompted by and ok deraadt@

Enhance '-g' to create a default GPT label in addition to the protective MBR. If '-b' is specified an EFI System partition of the requested size is created. All remaining space is put into an OpenBSD partition. Minimal enhancement necessary for upcoming UEFI install support. Committed first to flush out any unexpected impacts on 'normal' MBR operation and install media. ok deraadt@
