5bd649ef31 uefi: detect unmounted ESP partitions (Fixes: #1405) 
Mount these while writing out updates.
Leave them mounted when done (you gotta reboot anyway).

1b5f1da202 uefi: use tpm2-tss library to read PCR values 
Using the library instead of the command line tools provides a more
stable interface. This implementation only fetches PCR 0 for all
available hash algorithms since this is the only PCR that is actually
used in fwupd.

26d3da4074 uefi: Fix a libasan failure when reading a UEFI variable 
It seems some older versions of libefi var incorrectly build the 'length' value
in the DP returned from efi_generate_file_device_path(). This means we copy past
the end of the allocated buffer when parsing the efi_update_info_t structure.

This bug seems fixed in efivar git master, and this fix is only going to help
people with older efivar versions. It's probably a good thing to be a bit more
paranoid about EFI variable data anyway.

5d9984e5ad uefi: add a new option to specify the os name 
fu_uefi_get_esp_path_for_os() generates the path to the OS directory
based on "ID" in /etc/os-release, and it may not work for some distros.

Take openSUSE as an example, the "ID" for openSUSE Leap is
"opensuse-leap" and that for openSUSE Tumbleweed is "opensuse-tumbleweed".
However, both of them use the same OS directory in the ESP, i.e.
"/EFI/opensuse".

This commit adds a new build option, efi_os_dir, to allow the packager to
specify the name of OS directory at build time instead of the runtime
detection.

b56015ed3f uefi: Add the PCR0 value as the device checksum for system firmware 
We can't actually access the UEFI ROM from userspace, but the PCR0 is a hash
built from the ROM itself. We could use this value to ensure the firmware has
been written correctly, and that the PCR0 matches the expected value specified
in the metadata.

481aa2a923 Port from libappstream-glib to libxmlb 
The libxmlb library is much faster to query, and does not require the daemon
to parse the XML metadata at startup. It's a zero-copy mmap design that is more
modern and less clunky.

RSS has reduced from 3Mb (peak 3.61Mb) to 1Mb (peak 1.07Mb) and the startup
time has gone from 280ms to 250ms.

57746cb839 Add the Meson build system as an alternate to autotools 
Automake and autoconf are impossible to fully understand and Meson now provides
everything we need for a much smaller, faster, and more understandable build.
