ACPICA: debugger: remove leading whitespaces when converting a string to a buffer

ACPICA commit 1b7228072f254a5b02625586ff7d561757b7fc2d

By removing leading whitespaces, the conversion computes the
correct number of elements in a given buffer or field encoding
that contains leading whitespaces.

ACPICA: Divergence: remove unwanted spaces for typedef

ACPICA commit b2294cae776f5a66a7697414b21949d307e6856f

This patch removes unwanted spaces for typedef. This solution doesn't cover
function types.

Note that the linuxize result of this commit is very giant and should have
many conflicts against the current Linux upstream. Thus it is required to
modify the linuxize result of this commit and the commits around it
manually in order to have them merged to the Linux upstream. Since this is
very costy, we should do this only once, and if we can't ensure to do this
only once, we need to revert the Linux code to the wrong indentation result
before merging the linuxize result of this commit. Lv Zheng.

ACPICA: Utilities: Update for strtoul64 merger

ACPICA commit 795e136d2ac77c1c8b091fba019b5fe36a44a323

Fixes a problem with the merger of the two internal versions
of this function. Make the maximum integer width (32-bit or
64-bit) a parameter to the function so that it no longer
exclusively uses the integer width specified in the DSDT/SSDT.

ACPICA: debugger: dbconvert: free pld_info on error return path

ACPICA commit 23e644670539e23818fa81e2af5e89ad6657e75c

A failed allocation of new_buffer causes a leak of pld_info
because the error return path fails to free pld_info. Ensure
it is freed on the error exit path.
